[0003] [Patent Document 1] JP 2005-309922 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, when a color of a specific component of a building is arbitrarily selected from a coordination database, the color balance may be lost due to the relationship between the color of the specific component and the colors of other components. In this respect, there is room for improvement in the system, method, and program for coordinating buildings. [Means for solving the problem]

[0005] (1) A coordination system for a building that solves the above-mentioned problems is a coordination system that coordinates the color of a target part of a building, wherein components that make up the target part and whose colors are fixed in advance are defined as fixed components, and components that make up the target part and whose colors are selected are defined as selected components, and the system includes: a memory unit that stores compatibility data indicating the compatibility of each pair of multiple fixed colors that are set as colors that the fixed components can take and each of multiple selected colors that are set as colors that the selected components can take; a fixed color setting unit that sets the fixed color of the fixed component by selecting from the multiple fixed colors; a recommended color extraction unit that extracts the recommended color from the multiple selected colors as a recommended color for the selected component based on the fixed color of the fixed component and the compatibility data; and an output unit that outputs the recommended color, wherein the compatibility data includes pairs of each of the multiple fixed colors and each of the multiple selected colors, and a compatibility value linked to each pair. According to this configuration, the colors of the components in the target portion of the building are configured to be colors that are compatible with each other, thereby providing a harmonious coordination for the target portion of the building.

[0006] (2) In the building coordination system of (1) above, the recommended color extraction unit extracts selected colors having a compatibility value higher than a predetermined value from among the compatibility values ​​of each pair based on the fixed colors of the fixed components and the compatibility data as the recommended colors for the colors of the selected components, or extracts a predetermined number of selected colors in descending order of compatibility value from among the compatibility values ​​of each pair as the recommended colors. With this configuration, colors that are compatible with the colors of the fixed components can be accurately selected as the colors of the selected components.

[0007] (3) In the coordination system for buildings described in (1) or (2) above, the recommended color extraction unit extracts, for an additional component different from the fixed component and the selected component, a color that is compatible with the recommended color extracted for the selected component from among a plurality of colors that the additional component may have, as a recommended additional component color for the additional component. With this configuration, it is possible to select, for the additional component, a recommended additional component color that is compatible with the selected component.

[0008] (4) In the coordination system for a building according to any one of (1) to (3) above, the output unit outputs the target part colored based on the recommended color, the fixed color, and shape data of the target part. With this configuration, an image diagram of the target part can be output.

[0009] (5) In the coordination system for a building according to any one of (1) to (4) above, the storage unit further stores compatibility data between selected components indicating compatibility of each pair of colors between each of a plurality of selected colors that one of the two selected components can take and a plurality of selected colors that the other of the two selected components can take, and the recommended color extraction unit further stores compatibility data between the selected components indicating compatibility of each pair of colors between the fixed color of the fixed component and the selected component as the recommended colors for the colors of the two selected components. Phase The recommended color is extracted based on the compatibility data between the selected components and the property data between the selected components. With this configuration, the recommended color can be selected so that the recommended color is compatible with the color of the fixed component and is compatible with the color of the two selected components.

[0010] (6) A method for coordinating a building that solves the above-mentioned problems is a method for coordinating the color of a target part of a building, comprising: defining components that constitute the target part and whose colors are fixed in advance as fixed components; defining components that constitute the target part and whose colors are selected as selected components; and preparing compatibility data indicating the compatibility of each pair of multiple fixed colors that are set as colors that the fixed components can take and each of multiple selected colors that are set as colors that the selected components can take; a fixed color setting process for setting the fixed color of the fixed component by selecting from the multiple fixed colors; a recommended color extraction process for extracting the recommended color from the multiple selected colors as a recommended color for the selected component based on the fixed color of the fixed component and the compatibility data; and an output process for outputting the recommended color, wherein the compatibility data includes pairs of each of the multiple fixed colors and each of the multiple selected colors, and a compatibility value linked to each pair. According to this configuration, the colors of the components in the target portion of the building are configured to be colors that are compatible with each other, thereby providing a harmonious coordination for the target portion of the building.

[0011] (7) In the method for coordinating buildings according to (6) above, in the recommended color extraction step, a selected color having a compatibility value higher than a predetermined value is extracted as the recommended color for the color of the selected component based on the fixed color of the fixed component and the compatibility data, or a predetermined number of selected colors in descending order of compatibility value for each pair are extracted as the recommended colors. With this configuration, a color that is compatible with the color of the fixed component can be accurately selected as the color of the selected component.

[0012] (8) In the method for coordinating architecture according to (6) or (7) above, the recommended color extraction step further includes extracting, for an additional component different from the fixed component and the selected component, a color that is compatible with the recommended color extracted for the selected component from a plurality of colors that the additional component can have, as a recommended additional component color for the additional component. With this configuration, a recommended additional component color that is compatible with the selected component can be selected for the additional component.

[0013] (9) In the method for coordinating a building according to any one of (6) to (8) above, the output step outputs the target part colored based on the recommended color, the fixed color, and shape data of the target part. With this configuration, an image of the target part can be output.

[0014] (10) In the method for coordinating a building according to any one of (6) to (9) above, compatibility data between selected components is prepared, which indicates compatibility between each pair of multiple selected colors that one of two selected components can take and multiple selected colors that the other of the two selected components can take, and in the recommended color extraction step, the recommended colors for the two selected components are the fixed color of the fixed component and the color compatibility between the fixed component and the selected component. Phase The recommended color is extracted based on the compatibility data between the selected components and the property data between the selected components. With this configuration, the recommended color can be selected so that the recommended color is compatible with the color of the fixed component and is compatible with the color of the two selected components.

[0015] (11) A coordination program for a building that solves the above-mentioned problem is a coordination program for a building that causes a computer to coordinate the color of a target part of a building, the program defining components that constitute the target part and whose colors are fixed in advance as fixed components, and components that constitute the target part and whose colors are selected as selected components, and including a reading step of reading compatibility data indicating the compatibility of each pair of multiple fixed colors that are set as colors that the fixed components can take and each of multiple selected colors that are set as colors that the selected components can take, a fixed color setting step of setting the fixed color of the fixed component by selecting from the multiple fixed colors, a recommended color extraction step of extracting the recommended color from the multiple selected colors as a recommended color for the selected component based on the fixed color of the fixed component and the compatibility data, and an output step of outputting the recommended color, wherein the compatibility data includes pairs of each of the multiple fixed colors and each of the multiple selected colors, and a compatibility value linked to each pair. According to this configuration, the colors of the components in the target portion of the building are configured to be colors that are compatible with each other, thereby providing a harmonious coordination for the target portion of the building.

[0018] First Embodiment 1 to 10, a coordination system 10 for a building 1 according to the present embodiment will be described. The coordination system 10 coordinates the color of a target portion 2 in the building 1. Examples of the building 1 to be coordinated include a house, an apartment building, a store, a public facility, and an inn.

[0019] The target part 2 of the coordination is the exterior or interior of the building 1. In the description of this embodiment, the target part 2 of the coordination is the exterior of the building 1. The exterior of the building 1 may be only the exterior of the building itself, or the entire exterior including the building itself and the exterior structure. In this embodiment, the target part 2 is the entire exterior including the building itself and the exterior structure. The building itself is a house.

[0020] In one example, the coordinate system 10 is used when renovating the exterior of the building 1. Specifically, the coordinate system 10 is used when the exterior of the building 1 is to be changed to a different appearance from the pre-renovation appearance through renovation. The coordinate system 10 presets the colors of some of the components 30 that make up the exterior of the building 1, and then finds colors for the other components 30 that are compatible with the preset colors. The coordinate system 10 proposes an exterior with colors that harmonize with the overall appearance of the building 1.

[0021] The appearance of the building 1 is determined by the color balance of the components 30 of the building 1's appearance. The components 30 of the building 1's appearance are the sash 3, the roof 4, the exterior wall 5, the eaves 6, the fence 7 as an exterior structure, the plantings 8 as an exterior structure, the balcony coping, the front door, etc. The main components that affect the appearance are the color of the roof 4, the color of the sash 3, and the color of the exterior wall 5. Of these, the color of the roof 4 and the color of the sash 3 are often maintained as they are. For this reason, in one example, the color of the roof 4 and the color of the sash 3 are set to the existing color.

[0022] A conceptual diagram of the coordination system 10 is shown in FIG. 1. As shown in FIG. 1, the coordination system 10 uses compatibility data 35 based on the set color of the roof 4 and the color of the sash 3 (described later as the color of the fixed component 30A) to find a color of the exterior wall 5 (described later as the color of the selection component 30B) that is compatible with these colors. The coordination system 10 then creates an image of the exterior of the building 1 based on the set color of the roof 4, the color of the sash 3, and the found color of the exterior wall 5, and outputs the image. This allows the user to get an idea of ​​what the building 1 will look like after renovation.

[0023] The coordinate system 10 may be used not only for coordinating the exterior appearance when renovating the building 1, but also for coordinating the exterior appearance of a newly constructed building 1. The coordinate system 10 may be used when a designer considers the exterior appearance of a new building 1. The coordinate system 10 may be used for coordinating the interior appearance of the building 1. Specific examples of the coordinate system 10 will be described below. In addition, an example of when the coordinate system 10 is used in coordinating the exterior appearance when renovating the building 1 will be described.

[0024] [Coordination System] 2, the coordination system 10 includes a first storage unit 11, a second storage unit 12, a fixed color setting unit 15, a recommended color extraction unit 16, and an output unit 20. The coordination system 10 may further include a building model setting unit 13, a component setting unit 14, an exterior wall painting specification setting unit 17, a paint type setting unit 18, an exterior wall pattern setting unit 19, and an input unit 21.

[0025] [Fixed components] In the coordination system 10, the fixed component 30A is defined as follows: The fixed component 30A is a component 30 that constitutes the target portion 2 of coordination, and is a component 30 whose color is fixed in advance.

[0026] In the coordinate system 10, the fixed component 30A is configured to be selectable by the user. In one example, the fixed component 30A is selected by the user from the exterior components 30 of the building 1. The fixed component 30A may also be selected from a first predetermined component that is set in advance among the exterior components 30 of the building 1.

[0027] In this embodiment, the fixed components 30A are selected from the first predetermined components by the user's designation via the input unit 21. Specifically, the fixed components 30A are set by the component setting unit 14 based on the user's designation via the input unit 21. In one example, the first predetermined components include the roof 4, the sash 3, and the eaves 6. The roof 4 and the sash 3 are among the main elements that affect the appearance, and in many cases of renovation, the existing color of the roof 4 and the sash 3 is difficult to change. For this reason, in the example of this embodiment, the sash 3 and the roof 4 are set as the fixed components 30A.

[0028] [Selected Components] In the coordination system 10, the selection component 30B is defined as follows: The selection component 30B is a component 30 that constitutes the target portion 2 of the coordination, and is a component 30 for which the color is selected by the coordination system 10.

[0029] In the coordination system 10, the selection component 30B may be configured to be selectable by a user. The selected component 30B is selected from the exterior components 30 of the building 1. The selected component 30B may be selected from a second predetermined component that is set in advance among the components 30 of the exterior of the building 1. In one example, the second predetermined component includes the exterior wall 5.

[0030] In the coordinate system 10 in this embodiment, the type of the selection component 30B is fixed to the exterior wall 5. The type of the selection component 30B is not limited to the exterior wall 5. In other coordinate systems 10, the type of the selection component 30B may be the roof 4.

[0031] In this embodiment, the number of selection components 30B varies depending on the type of exterior wall paint specification. The coordination system 10 in this embodiment has two types of exterior wall paint specifications. One of the two exterior wall paint specifications is one-color paint, and the other is two-color paint. In the case of one-color paint, one exterior wall 5 covering the entire exterior surface of the building 1 is set as the selection component 30B. In the case of two-color paint, the exterior wall 5 covering a part of the exterior surface of the building 1 and the exterior wall 5 covering the other part of the exterior surface of the building 1 are set as the selection component 30B. For example, in the case of two-color paint, the exterior wall 5 of the first floor and the exterior wall 5 of the second floor are separate selection components 30B. The exterior wall paint specification is set by the exterior wall paint specification setting unit 17 based on the user's designation.

[0032] [1st memory section] The first storage unit 11 includes a storage medium such as a semiconductor memory, such as a random access memory (RAM), a read only memory (ROM), or a solid state drive (SSD), a hard disk, an optical disk, a magnetic disk, or a magnetic tape.

[0033] The first storage unit 11 stores a building model 41 to be coordinated. Several houses having typical shapes selected from among general houses are stored as the building models 41 in the first storage unit 11. The building model 41 includes a part 2 to be coordinated. In another example, the first storage unit 11 may store a specific building model designated by a user or a seller as a coordination target. The specific building model is a model formed from a CAD drawing of a building. The specific building model may be a building to be built in the future, or may be an existing building.

[0034] The first storage unit 11 stores shape data of a target portion 2 in the building 1 for each building model 41. In this embodiment, the target portion 2 of the coordination is the exterior of the building 1. Therefore, the first storage unit 11 stores CAD data of the components 30 that make up the exterior of the building 1 as shape data.

[0035] The first storage unit 11 stores, for each building model 41, the type of exterior wall paint specification and paint information corresponding to the exterior wall paint specification in association with each other. As described above, there are two types of exterior wall paint specifications. The first type of exterior wall paint specification is one-color paint. The second type of exterior wall paint specification is two-color paint. The first storage unit 11 stores the paint information in association with the specification of the two-color exterior wall 5 for each building model 41. The paint information is information indicating the color area of ​​the first color and the color area of ​​the second color in the building model 41. For example, the color area of ​​the first color is set as the exterior wall area of ​​the first floor. The color area of ​​the second color is set as the exterior wall area of ​​the second floor. In another example, the color area of ​​the first color is set as the exterior wall area of ​​the first and second floors. The color area of ​​the second color is set as the loggia wall area.

[0036] Furthermore, the first storage unit 11 stores an exterior wall pattern 42. The first storage unit 11 stores a typical exterior wall pattern 42 used for a house. The exterior wall pattern 42 is information used in the output unit 20 when creating an image diagram of the building 1. By using the exterior wall pattern 42, the image diagram of the building 1 can be made closer to the actual building 1.

[0037] [Second memory section] The second storage unit 12 includes a storage medium. Examples of the storage medium are the same as those given in the description of the first storage unit 11. The first storage unit 11 and the second storage unit 12 may each be configured as a part of a single storage medium. The second storage unit 12 may be configured by a different type of storage medium from the first storage unit 11. The second storage unit 12 may also be configured by the same type of storage medium as the first storage unit 11. The first storage unit 11 and the second storage unit 12 may be configured as separate storage units, or may be configured as a single storage unit.

[0038] The second storage unit 12 stores the exterior components 30 of the building 1. Specifically, the second storage unit 12 stores the exterior components 30 of the building 1 in association with the building model 41. In this embodiment, the exterior components 30 are the roof 4, the exterior wall 5, the sash 3, the eaves 6, the fence 7, and the plantings 8 as the exterior structure. The exterior components 30 may also include gutters, window lattices, a front door, a gate wall, and the like. The exterior components 30 may be set for each building model 41.

[0039] The second storage unit 12 stores, for each fixed component 30A, a plurality of fixed colors 31 that the fixed component 30A can take. Furthermore, the second storage unit 12 stores, for each selection component 30B, a plurality of selection colors 32 that the selection component 30B can take.

[0040] Specifically, for a sash 3 as a fixed component 30A, the second storage unit 12 stores several fixed colors 31 that the sash 3 can take. Furthermore, for a roof 4 as a fixed component 30A, the second storage unit 12 stores several fixed colors 31 that the roof 4 can take. Furthermore, for an exterior wall 5 as a selective component 30B, the second storage unit 12 stores several selective colors 32 that the exterior wall 5 can take.

[0041] Furthermore, the second storage unit 12 stores compatibility data 35. The compatibility data 35 is data indicating the compatibility between the selection component 30B and the fixed component 30A. The compatibility data 35 indicates the compatibility of each pair of colors between each of a plurality of fixed colors 31 set as colors that the fixed component 30A can take and each of a plurality of selection colors 32 set as colors that the selection component 30B can take. Specific examples of the compatibility data 35 will be described below.

[0042] [Compatibility data] The compatibility data 35 includes pairs of each of the multiple fixed colors 31 and each of the multiple selectable colors 32, and a compatibility value linked to each pair. The compatibility value indicates the compatibility between the fixed color 31 and the selectable color 32. The data format of the compatibility data 35 is not limited. The data format of the compatibility data 35 may be table-format data. The data format of the compatibility data 35 may be array data format.

[0043] An example of the compatibility data 35 will be described with reference to FIG. In this example, the sash 3 is set to the fixed component 30A. The roof 4 is set to the fixed component 30A. The first exterior wall 5A is set to the optional component 30B. The second exterior wall 5B is set to the optional component 30B.

[0044] In the compatibility data 35, the sash 3 has multiple fixed colors 31 that can be taken as the color of the sash 3. The roof 4 has multiple fixed colors 31 that can be taken as the color of the roof 4. The first exterior wall 5A has multiple selectable colors 32 that can be taken as the color of the first exterior wall 5A. The second exterior wall 5B has multiple selectable colors 32 that can be taken as the color of the second exterior wall 5B.

[0045] The compatibility data 35 includes first compatibility data 35A, second compatibility data 35B, and third compatibility data 35C. The first compatibility data 35A includes each pair of the multiple fixed colors 31 of the sash 3 and each of the multiple selection colors 32 of the first exterior wall 5A, and a compatibility value linked to each pair. The second compatibility data 35B includes each pair of the multiple fixed colors 31 of the roof 4 and each of the multiple selection colors 32 of the first exterior wall 5A, and a compatibility value linked to each pair. The third compatibility data 35C includes each pair of the multiple selection colors 32 of the first outer wall 5A and each selection color 32 of the second outer wall 5B, and a compatibility value associated with each pair.

[0046] In the example of FIG. 3, the compatibility value has four values. In FIG. 3, the compatibility values ​​are indicated by a double circle, a circle, a triangle, and a cross, in order of color compatibility. For comparison calculations, the compatibility values ​​are associated with numerical values ​​in the recommended color extraction unit 16. The better the color compatibility, the higher the compatibility value. For example, a double circle is associated with 4. A circle is associated with 3. A triangle is associated with 2. A cross is associated with 1.

[0047] Furthermore, the compatibility data 35 is provided for each type of paint for the selected component 30B (the exterior wall 5 in this embodiment). Examples of paint types include polychromatic and monochromatic. Polychromatic is a color that is composed of multiple overlapping colors. Monochromatic is a color that is composed of one color. The color variations of the selection color 32 that the exterior wall 5 can have when the paint type is monochromatic are different from the color variations of the selection color 32 that the exterior wall 5 can have when the paint type is polychromatic. For this reason, compatibility data 35 is provided for each paint type of the exterior wall 5. Note that the color variations of the fixed color 31 that the fixed components 30A (the sash 3 and the roof 4 in this embodiment) can have are the same regardless of the paint type of the selection component 30B.

[0048] Specifically, the first compatibility data 35A is provided for each type of paint for the exterior wall 5. The second compatibility data 35B is provided for each type of paint for the exterior wall 5. The third compatibility data 35C is provided for each type of paint for the exterior wall 5.

[0049] In the polychromatic compatibility data 35, the multiple types of selection colors 32 that the first exterior wall 5A and the second exterior wall 5B can have are set as polychromatic colors. In the monochromatic compatibility data 35, the multiple types of selection colors 32 that the first exterior wall 5A and the second exterior wall 5B can have are set as monochromatic colors.

[0050] Whether to use the monochromatic compatibility data 35 or the polychromatic compatibility data 35 is set by the user via the input unit 21. In this embodiment, a compatibility table which is the monochromatic compatibility data 35 and a compatibility table which is the polychromatic compatibility data 35 are stored in the second storage unit 12, and the compatibility table according to the paint type set by the paint type setting unit 18 based on the user's instruction is used. Note that the compatibility data 35 shown in Fig. 3 is the monochromatic compatibility data 35. The polychromatic compatibility data 35 is not shown in the figure.

[0051] The second storage unit 12 may store other compatibility data in addition to the compatibility data 35 described above. With reference to FIG. 4, the other compatibility data (hereinafter, additional compatibility data 36) will be described. The additional compatibility data 36 is data that is referenced when selecting the color of the additional component 30C for the components 30 other than the fixed component 30A (hereinafter, the additional component 30C) among the components 30 of the building 1. For example, after the color of the first exterior wall 5A is set as the selected component 30B, the additional compatibility data 36 is referenced when selecting the color of the additional component 30C.

[0052] Specifically, the additional compatibility data 36 is data indicating the compatibility between the additional component 30C and the selected component 30B for the additional component 30C. The structure of the additional compatibility data 36 is the same as the structure of the first compatibility data 35A or the second compatibility data 35B described above. In this embodiment, the additional compatibility data 36 includes the first additional compatibility data 36A, the second additional compatibility data 36B, and the third additional compatibility data 36C.

[0053] The first additional compatibility data 36A includes pairs of each of the multiple colors of the eaves 6 and each of the multiple selection colors 32 of the first exterior wall 5A, and a compatibility value linked to each pair. The second additional compatibility data 36B includes pairs of each of the multiple colors of the fence 7 and each of the multiple selection colors 32 of the first exterior wall 5A, and a compatibility value associated with each pair. The third additional compatibility data 36C includes pairs of each of the multiple colors of the planting 8 and each of the multiple selection colors 32 of the first exterior wall 5A, and a compatibility value associated with each pair.

[0054] According to the additional compatibility data 36, ​​when the selected color 32 of the first exterior wall 5A is set, the color of the eaves 6, the color of the fence 7, and the color of the plants 8 that are compatible with the selected color 32 of the first exterior wall 5A can be selected. In one example, the additional compatibility data 36 is referred to when changing the color of the additional component 30C after the image drawing of the exterior of the building 1 is completed.

[0055] An example of how the compatibility data 35 is used will be described with reference to FIG. When the exterior wall paint specification is one-color paint, since the exterior wall 5 is one color, there is no need to consider the compatibility between the first exterior wall 5A and the second exterior wall 5B. For this reason, the third compatibility data 35C indicating the compatibility between the first exterior wall 5A and the second exterior wall 5B is not used. Therefore, when the exterior wall paint specification is one-color paint and the sash 3 and the roof 4 are set as the fixed components 30A, the first compatibility data 35A and the second compatibility data 35B are used to extract the recommended color 33 for the first exterior wall 5A.

[0056] When the exterior wall painting specification is two-tone painting, the exterior wall 5 is painted in two colors, so it is necessary to consider the compatibility between the first exterior wall 5A and the second exterior wall 5B. For this reason, the third compatibility data 35C indicating the compatibility between the first exterior wall 5A and the second exterior wall 5B is used. Therefore, when the exterior wall painting specification is two-tone painting and the sash 3 and the roof 4 are set as the fixed components 30A, the first compatibility data 35A, the second compatibility data 35B, and the third compatibility data 35C are used to extract the recommended colors 53 for the first exterior wall 5A and the second exterior wall 5B.

[0057] [Input section] The input unit 21 is a device that accepts user specifications. One example of the input unit 21 is a touch panel. Other examples of the input unit 21 are a keyboard or a mouse. The input unit 21 accepts user selection of options displayed on the display screen of the display device 25.

When the user specifies the color of the sash 3, the fixed color setting unit 15 sets the color of the sash 3 specified by the user as the fixed color 31 of the sash 3 as the fixed component 30A. In this way, in coordination, the color of the fixed component 30A is fixed first.

[0070] [Recommended color extraction section] The recommended color extractor 16 extracts recommended colors 33 from a plurality of selected colors 32 based on the fixed colors 31 of the fixed component 30A and compatibility data 35 as recommended colors 33 for the color of the selected component 30B.

[0071] Specifically, the recommended color extraction unit 16 extracts, as the recommended color 33 for the color of the selected component 30B, the selected color 32 having a compatibility value higher than a predetermined value from the compatibility values ​​of each pair based on the fixed color 31 of the fixed component 30A and the compatibility data 35.

[0072] Referring to Figure 6, a specific example of the procedure for finding the recommended color 33 for the first exterior wall 5A when the exterior wall painting specification is a single-color paint and the first exterior wall 5A is set as the selection component 30B will be described.

[0073] The recommended color extraction unit 16 extracts a recommended color 33 for the first exterior wall 5A for the sash 3 as a primary recommended color 33A based on the first compatibility data 35A indicating the compatibility between the sash 3 and the first exterior wall 5A and the fixed color 31 of the sash 3. More specifically, the recommended color extraction unit 16 extracts pairs having a compatibility value higher than a predetermined value from among the compatibility values ​​of pairs of the fixed color 31 of the sash 3 and the multiple selected colors 32 of the first exterior wall 5A. Then, the recommended color extraction unit 16 sets the selected color 32 of the first exterior wall 5A of each extracted pair as the primary recommended color 33A for the sash 3.

[0074] The recommended color extraction unit 16 extracts the recommended color 33 of the first exterior wall 5A for the roof 4 as the primary recommended color 33A based on the second compatibility data 35B indicating the compatibility between the roof 4 and the first exterior wall 5A and the fixed color 31 of the roof 4. More specifically, the recommended color extraction unit 16 extracts pairs having a compatibility value higher than a predetermined value from among the compatibility values ​​of each pair of the fixed color 31 of the roof 4 and the multiple selected colors 32 of the first exterior wall 5A. Then, the recommended color extraction unit 16 sets the selected color 32 of the first exterior wall 5A of each extracted pair as the primary recommended color 33A for the roof 4.

[0075] Then, the recommended color extraction unit 16 sets the selected color 32 of the first exterior wall 5A, which has been extracted as the primary recommended color 33A for the sash 3 and the primary recommended color 33A for the roof 4, as a recommended color 33. In this way, the recommended color extraction unit 16 extracts a color that is compatible with both the sash 3 and the roof 4 as the recommended color 33.

[0076] 7 shows additional compatibility data 36 when recommended color 33 is set for first exterior wall 5A. Recommended color extraction unit 16 extracts a color that is compatible with recommended color 33 set for first exterior wall 5A from a plurality of colors that additional component 30C can take, as additional element recommended color 34 for additional component 30C. In FIG. 7, for each additional component 30C, a color that is compatible with recommended color 33 for first exterior wall 5A is highlighted with a bold solid line as additional element recommended color 34.

[0077] [Output section] The output section 20 will be described with reference to FIGS. The output unit 20 outputs an image of the target portion 2 colored based on the recommended color 33, the fixed color 31, and the shape data of the target portion 2. In this embodiment, the target portion 2 is the exterior of the building 1.

[0078] Specifically, the output unit 20 applies the recommended color 33 to the first exterior wall 5A, the fixed color 31 to the roof 4, and the fixed color 31 to the sash 3 for the shape data of the preselected building model 41, thereby forming an image diagram of the colored exterior of the building 1. The building 1 shown in the image diagram has the first exterior wall 5A of the recommended color 33, the sash 3 of the user-specified fixed color 31, and the roof 4 of the user-specified fixed color 31. The output unit 20 outputs the image diagram of the exterior of the colored building model 41 to the display device 25.

[0079] Fig. 8 is a diagram shown on the display screen of the display device 25 when there are four recommended colors 33 for the first exterior wall 5A. Fig. 8 shows image diagrams of the four coordinated recommended colors 33 for the exterior of the building model 41. The user can select one of the four image diagrams for the exterior of the building model 41 by specifying it via the input unit 21.

[0080] 9 shows an image diagram selected by a user. A color change button panel 27 is displayed near the image diagram. The output unit 20 outputs the color change button panel 27 for the building model 41 related to the image diagram to the display device 25.

[0081] The color change button panel 27 displays buttons 28 of components 30 that constitute the exterior of the building 1, and a color selection palette 29 of colors that each of the components 30 can have. The color selection palette 29 appears when a component 30 is selected in the color change button panel 27. The components 30 in the color change button panel 27 may include a fixed component 30A, a selected component 30B, and an additional component 30C. Examples of the components 30 in the color change button panel 27 are the sash 3, the roof 4, the exterior wall 5, the eaves 6, the fence 7, and the planting 8. In this embodiment, the components 30 in the color change button panel 27 include a selected component 30B and an additional component 30C. When a color is a color that is compatible with the color of the first exterior wall 5A, a mark 29X indicating a recommendation is added to the display location of the color in the color selection palette 29. The user can select a color by referring to the mark 29X. The color change button panel 27 allows the user to further change the color of the components 30 from the image diagram.

[0082] In the building 1, the recommended color 33 of the first exterior wall 5A matches both the user-specified fixed color 31 for the sash 3 and the user-specified fixed color 31 for the roof 4. Therefore, the appearance of the building 1 is harmonious as a whole.

[0083] The output destination of the output unit 20 is not limited to the display device 25. The output unit 20 may output an image of the target part 2 to a device with a display unit. The display device 25 is a monitor. The device with a display unit is a television, a mobile phone, a smartphone, a personal computer, or a tablet computer.

[0084] The operation of the coordinate system 10 will be described with reference to FIG. In a first step S1, the building model setting unit 13 sets the building model 41 based on a user's specification via the input unit 21.

[0085] In the second step S2, the paint type setting unit 18 sets the paint type based on the user's specification via the input unit 21. Specifically, the paint type setting unit 18 sets polychromatic color or monochromatic color for the paint type of the exterior wall 5. The paint type setting unit 18 prepares a compatibility table of compatibility data 35 according to the set paint type.

[0086] In a third step S3, the fixed color setting section 15 sets a fixed color 31 for the sash 3 based on a user's designation via the input section 21.

[0087] In a fourth step S4, the fixed color setting unit 15 sets a fixed color 31 for the roof 4 based on a user's designation via the input unit 21.

[0088] In the fifth step S5, the exterior wall paint specification setting unit 17 sets the exterior wall paint specification based on the user's specification via the input unit 21. Specifically, the exterior wall paint specification setting unit 17 sets one-color paint or two-color paint for the exterior wall paint specification. The setting of the exterior wall paint specification switches the method of setting the recommended color 33 for the exterior wall 5 executed by the recommended color extraction unit 16. The method of setting the recommended color 33 for the exterior wall 5 in one-color paint is the above-mentioned method shown in this embodiment. The method of setting the recommended color 33 for the exterior wall 5 in two-color paint is the method described later and shown in the second embodiment.

[0089] In a sixth step S6, the exterior wall pattern setting unit 19 sets the exterior wall pattern 42 based on the user's designation via the input unit 21. Incidentally, the processing order of the first step S1 to the sixth step S6 may be interchanged as long as no contradiction occurs.

[0090] In a seventh step S7, the recommended color extraction unit 16 extracts a recommended color 33 for the exterior wall 5 based on the information on whether it is one-tone or two-tone paint, the fixed color 31 for the sash 3, the fixed color 31 for the roof 4, and the compatibility data 35. Furthermore, for the eaves 6, fence 7, and plantings 8 as additional components 30C, the recommended color extraction unit 16 extracts, based on additional compatibility data 36, ​​colors that are compatible with the recommended color 33 extracted for the exterior wall 5 as additional component recommended colors 34.

[0091] In an eighth step S8, the output unit 20 forms an image of the exterior of the building 1 using the building model 41, the fixed color 31 of the sash 3, the fixed color 31 of the roof 4, the exterior wall pattern 42, and the recommended color 33. Then, the output unit 20 outputs the image of the exterior of the building 1 to the display device 25. In addition, the output unit 20 causes the display device 25 to display a color selection palette 29 to allow the user to select colors for the eaves 6, the fence 7, and the plants 8 that are compatible with the recommended color 33 for the exterior wall 5.

[0092] [Operation of this embodiment] The operation of this embodiment will now be described. In the present coordination system 10, from among the components 30 that compose the exterior of the building 1, fixed components 30A, whose colors are preset, and selected components 30B, from which recommended colors 33 are found, are set. Then, using compatibility data 35 between the colors that the fixed components 30A can take and the colors that the selected components 30B can take, a color that is compatible with the fixed components 30A is found as the recommended color 33 recommended for the selected components 30B. This makes it possible to provide a harmonious coordination for the exterior of the building 1.

[0093] [Effects of this embodiment] The effects of this embodiment will be described. (1) The coordination system 10 includes a recommended color extraction unit 16. The recommended color extraction unit 16 extracts, as a recommended color 33 for the color of the selected component 30B, from a plurality of selected colors 32 based on the fixed color 31 of the fixed component 30A and compatibility data 35. According to this configuration, the colors of the components 30 in the target portion 2 of the building 1 are configured with colors that are compatible with each other, so that a harmonious coordination can be provided for the target portion 2 of the building 1.

[0094] (2) The recommended color extraction unit 16 extracts selected colors 32 with a higher compatibility value than a predetermined value from among the compatibility values ​​of each pair based on the fixed color 31 of the fixed component 30A and the compatibility data 35 as the recommended color 33 for the color of the selection component 30B. Alternatively, the recommended color extraction unit 16 extracts selected colors 32 with a higher compatibility value from among the compatibility values ​​of each pair based on the fixed color 31 of the fixed component 30A and the compatibility data 35 as the recommended color 33 for the color of the selection component 30B. According to this configuration, a color that is compatible with the color of the fixed component 30A can be accurately selected as the color of the selection component 30B. Specifically, "can be accurately selected" means the following. When compatibility is determined by the sense of the designer, there is variation in the judgment of a compatible color. In contrast, in the present coordination system 10, the recommended color 33 that is considered to be compatible with the fixed color does not change for each process.

[0095] (3) The recommended color extraction unit 16 extracts, from among a plurality of colors that the additional component 30C can have, a color that is compatible with the recommended color 33 as an additional component recommended color 34. With this configuration, it is possible to select, for the additional component 30C, a recommended additional component color 34 that is compatible with the selected component 30B.

[0096] (4) The output unit 20 outputs an image of the target portion 2 colored based on the recommended color 33, the fixed color 31, and the shape data of the target portion 2. With this configuration, an image diagram of the target portion 2 can be output.

[0097] <Second embodiment> A coordinate system 10 according to the second embodiment will be described with reference to Fig. 11 and Fig. 12. In this embodiment, components common to the first embodiment are denoted by the same reference numerals as those in the first embodiment, and descriptions of overlapping components will be omitted.

[0098] In the first embodiment, an example of one-color painting will be described for the exterior wall 5 of the building 1. In contrast, in the present embodiment, an example of two-color painting will be described for the exterior wall 5 of the building 1. Hereinafter, the exterior wall 5 to which one of the two colors is applied will be referred to as a first exterior wall 5A. The exterior wall 5 to which the other color is applied will be referred to as a second exterior wall 5B.

[0099] A conceptual diagram of the coordination system 10 is shown in Fig. 11. As shown in Fig. 11, the coordination system 10 uses compatibility data 38 based on the color of the sash 3 and the color of the roof 4 in the first exterior wall 5A to find a second recommended color 51C for the first exterior wall 5A that is compatible with these colors.

[0100] The coordination system 10 uses the compatibility data 38 based on the color of the sash 3 and the color of the roof 4 in the second exterior wall 5B to find a second recommended color 52C for the second exterior wall 5B that is compatible with these colors.

[0101] Furthermore, based on the second recommended color 51C for the first exterior wall 5A and the second recommended color 52C for the second exterior wall 5B, the coordination system 10 uses compatibility data 38 to find a color that is compatible with the first exterior wall 5A and the second exterior wall 5B as a recommended color 53.

[0102] The coordinate system 10 creates an image of the exterior of the building 1 based on the color of the sash 3, the color of the roof 4, and the found recommended color 53 for the first exterior wall 5A and the recommended color 53 for the second exterior wall 5B, and outputs the image. This allows the user to get an idea of ​​what the building 1 will look like after renovation.

[0103] In this embodiment, the second storage unit 12 stores two types of compatibility data 38. The first type of compatibility data 38A is compatibility data 38 between the fixed component 30A and the selection component 30B. The first type of compatibility data 38A indicates the compatibility of each pair of colors between each of a plurality of fixed colors 31 set as colors that the fixed component 30A can take and each of a plurality of selection colors 32 set as colors that the selection component 30B can take. The first type of compatibility data 38A includes the first compatibility data 35A and the second compatibility data 35B of the first embodiment.

[0104] The second type of compatibility data 38B is the compatibility data 38 between the selected components 30B. The second type of compatibility data 38B indicates the compatibility of each pair of colors between a plurality of selection colors 32 that one of the two selection components 30B can have and a plurality of selection colors 32 that the other of the two selection components 30B can have. The second type of compatibility data 38B includes the third compatibility data 35C of the first embodiment. The third compatibility data 35C is shown in the first embodiment, so a description thereof will be omitted.

[0105] The first type of compatibility data 38A is provided for each pair of a fixed component 30A and a selected component 30B. The second type of compatibility data 38B is provided for each pair of one selected component 30B and another selected component 30B.

[0106] [Recommended color extraction section] The recommended color extraction unit 16 extracts recommended colors 53 as the colors of the two selected components 30B based on the fixed color 31 of the fixed component 30A, the compatibility data 38A between the fixed component 30A and the selected component 30B, and the compatibility data 38B between the selected components 30B.

[0107] Specifically, the recommended color extraction unit 16 extracts selected colors 32 having a compatibility value higher than a predetermined value from the compatibility values ​​of each pair as recommended colors 53 for the colors of the two selected components 30B based on the fixed color 31 of the fixed component 30A, the compatibility data 38A between the fixed component 30A and the selected component 30B, and the compatibility data 38B between the selected components 30B.

[0108] A specific example of a procedure for finding out the recommended colors 53 for the first exterior wall 5A and the second exterior wall 5B will be described with reference to Fig. 12. In this example, the first exterior wall 5A and the second exterior wall 5B are set as the selection components 30B.

[0109] [Step 1] In the first step, a second recommended color 51C for the first exterior wall 5A is extracted. The recommended color extraction unit 16 extracts a recommended color 53 for the first exterior wall 5A for the sash 3 as a primary recommended color 51A based on the first compatibility data 35A indicating the compatibility between the sash 3 and the first exterior wall 5A and the fixed color 31 of the sash 3. More specifically, the recommended color extraction unit 16 extracts pairs having a compatibility value higher than a predetermined value from among the compatibility values ​​of pairs of the fixed color 31 of the sash 3 and the multiple selected colors 32 of the first exterior wall 5A. Then, the recommended color extraction unit 16 sets the selected color 32 of the first exterior wall 5A of each extracted pair as the primary recommended color 51A for the sash 3.

[0110] The recommended color extraction unit 16 extracts a recommended color 53 for the first exterior wall 5A for the roof 4 as a primary recommended color 51B based on the second compatibility data 35B indicating the compatibility between the roof 4 and the first exterior wall 5A and the fixed color 31 of the roof 4. More specifically, the recommended color extraction unit 16 extracts pairs having a compatibility value higher than a predetermined value from among the compatibility values ​​of pairs of the fixed color 31 of the roof 4 and the multiple selected colors 32 of the first exterior wall 5A. Then, the recommended color extraction unit 16 sets the selected color 32 of the first exterior wall 5A of each extracted pair as the primary recommended color 51B for the roof 4.

[0111] Then, the recommended color extraction unit 16 sets the selected color 32 of the first exterior wall 5A, which has been extracted as the primary recommended color 51A for the sash 3 and the primary recommended color 51B for the roof 4, as the secondary recommended color 51C. In this manner, the recommended color extraction unit 16 extracts a color that is compatible with both the sash 3 and the roof 4 as the secondary recommended color 51C. In this embodiment, the fourth, fifth, sixth, and eleventh colors are extracted as the secondary recommended colors 51C for the first exterior wall 5A.

[0112] [Second Step] In the second procedure, a second recommended color 52C for the second exterior wall 5B is extracted. The fixed color 31 of the sash 3 in the second exterior wall 5B may be the same as the fixed color 31 of the sash 3 in the first exterior wall 5A, or may be a different color.

[0113] The recommended color extraction unit 16 extracts a recommended color 53 for the second exterior wall 5B for the sash 3 as a primary recommended color 52A based on the first compatibility data 35A indicating the compatibility between the sash 3 and the second exterior wall 5B and the fixed color 31 of the sash 3. More specifically, the recommended color extraction unit 16 extracts pairs having a compatibility value higher than a predetermined value from among the compatibility values ​​of pairs of the fixed color 31 of the sash 3 and the multiple selected colors 32 of the second exterior wall 5B. Then, the recommended color extraction unit 16 sets the selected color 32 of the second exterior wall 5B of each extracted pair as the primary recommended color 52A for the sash 3.

[0114] The recommended color extraction unit 16 extracts a recommended color 53 for the second exterior wall 5B for the roof 4 as a primary recommended color 52B based on the second compatibility data 35B indicating the compatibility between the roof 4 and the second exterior wall 5B and the fixed color 31 of the roof 4. More specifically, the recommended color extraction unit 16 extracts pairs having a compatibility value higher than a predetermined value from among the compatibility values ​​of pairs of the fixed color 31 of the roof 4 and the multiple selected colors 32 of the second exterior wall 5B. Then, the recommended color extraction unit 16 sets the selected color 32 of the second exterior wall 5B of each extracted pair as the primary recommended color 52B for the roof 4.

[0115] Then, the recommended color extraction unit 16 sets the selected color 32 of the second exterior wall 5B, which has been extracted as the primary recommended color 52A for the sash 3 and the primary recommended color 52B for the roof 4, as the secondary recommended color 52C. In this way, the recommended color extraction unit 16 extracts a color that is compatible with both the sash 3 and the roof 4 as the secondary recommended color 52C.

[0116] In this embodiment, the fixed color 31 of the sash 3 of the second exterior wall 5B is the same as the fixed color 31 of the sash 3 of the first exterior wall 5A, and the color of the roof 4 is common, so the secondary recommended color 52C for the second exterior wall 5B is the same as the secondary recommended color 51C for the first exterior wall 5A. That is, the fourth color, the fifth color, the sixth color, and the eleventh color are extracted as the secondary recommended color 52C for the second exterior wall 5B.

[0117] Furthermore, the recommended color extraction unit 16 extracts, based on the second recommended color 51C for the first exterior wall 5A, the second recommended color 52C for the second exterior wall 5B, and the third compatibility data 35C, a color that is compatible with each other from the second recommended color 51C for the first exterior wall 5A and the second recommended color 52C for the second exterior wall 5B, as a recommended color 53.

[0118] Specifically, the recommended color extraction unit 16 extracts compatible color combinations from the recommended values ​​of each set of four secondary recommended colors 51C for the first exterior wall 5A and four secondary recommended colors 52C for the second exterior wall 5B based on the third compatibility data 35C. In this embodiment, a predetermined number or more of recommended colors 53 are extracted. Specifically, a pair of a fourth color and a sixth color (hereinafter, group A) and a pair of a fifth color and a sixth color (hereinafter, group B) are extracted as pairs of recommended colors 53 for the first exterior wall 5A and the second exterior wall 5B. Group A has a compatibility value of a triangle, but since there is only one recommended pair excluding group A, two pairs are selected in this example.

[0119] [Effects of this embodiment] The effects of this embodiment will be described. In the coordination system 10, the recommended color extraction unit 16 extracts a recommended color 53 for two selected components 30B based on the fixed color 31 of the fixed component 30A, the compatibility data 38A between the fixed component 30A and the selected components 30B, and the compatibility data 38B between the selected components 30B. With this configuration, the recommended color 53 can be selected so that it is compatible with the color of the fixed component 30A and is compatible with the color of the two selected components 30B.

[0120] <Third embodiment> A coordination method for the building 1 according to the third embodiment will be described. In this embodiment, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and the description of the overlapping components will be omitted.

[0121] The method for coordinating the building 1 is a method for coordinating the color of the target portion 2 in the building 1.

[0122] [How to coordinate one-color painting] In the coordination method, the components 30 constituting the target portion 2, whose colors are fixed in advance, are defined as fixed components 30A. Also, the components 30 constituting the target portion 2, whose colors are selected, are defined as selected components 30B. For example, the sash 3 and roof 4 are defined as fixed components 30A. The exterior wall 5 is defined as selected component 30B.

[0123] The coordination method includes a preparation step, a fixed color setting step, a recommended color extraction step, and an output step.

According to this configuration, the colors of components 30 in target portion 2 of building 1 are composed of colors that are compatible with each other, so that harmonious coordination can be provided for target portion 2 of building 1.

[0134] (2) In the recommended color extraction step, selected colors 32 having a compatibility value higher than a predetermined value among the compatibility values ​​of each pair are extracted as recommended colors 33 for the color of selected component 30B based on fixed colors 31 of fixed component 30A and compatibility data 35. Alternatively, in the recommended color extraction step, selected colors 32 having a compatibility value higher than a predetermined value among the compatibility values ​​of each pair are extracted as recommended colors 33 for the color of selected component 30B based on fixed colors 31 of fixed component 30A and compatibility data 35.

[0138] <Fourth embodiment> A coordination program for a building 1 according to a fourth embodiment will be described. In this embodiment, components common to the first embodiment will be denoted by the same reference numerals as those in the first embodiment, and descriptions of overlapping components will be omitted.

[0139] The coordination program for the building 1 is a coordination program for the building 1 that causes a computer to coordinate the color of the target portion 2 in the building 1.

[0140] In the coordination program, the components 30 constituting the target portion 2, whose colors are fixed in advance, are defined as fixed components 30A. Also, the components 30 constituting the target portion 2, whose colors are selected, are defined as selected components 30B.

[0141] The coordinate program includes a reading step, a fixed color setting step, a recommended color extraction step, and an output step.

[0142] In the reading step, the shape data of the target part 2 and the compatibility data 35 are read from the storage device of the computer.

[0143] The compatibility data 35 indicates the compatibility of each pair of colors between a plurality of fixed colors 31 set as possible colors for the fixed component 30A and a plurality of selection colors 32 set as possible colors for the selection component 30B.

[0144] The compatibility data 35 includes pairs of each of the multiple fixed colors 31 and each of the multiple selection colors 32, and a compatibility value associated with each pair.

[0145] In the fixed color setting step, the computer is caused to set the fixed color 31 of the fixed component 30A by selecting from a plurality of fixed colors 31.

[0146] In the recommended color extraction step, the computer extracts recommended colors 33 from a plurality of selected colors 32 based on the fixed colors 31 of the set fixed component 30A and compatibility data 35 as recommended colors 33 for the color of the selected component 30B.

[0147] The recommended color extraction unit 16 causes the computer to extract, as a recommended color 33, a second color having a compatibility value higher than a predetermined value from the compatibility values ​​of each pair of a fixed color 31 in the compatibility data 35 and a second color that the selection component 30B can take.

[0148] Alternatively, the recommended color extraction unit 16 may cause the computer to extract a predetermined number of second colors in descending order of compatibility value from the compatibility values ​​of each pair of fixed color 31 in the compatibility data 35 and second colors that the selection component 30B can take, as recommended colors 33.

[0149] In the output step, the computer is caused to output the target portion 2 colored based on the recommended color 33, the fixed color 31, and the shape data of the target portion 2.

[0150] [Effects of this embodiment] The effects of this embodiment will be described. The coordination program for the building 1 includes a recommended color extraction step. In the recommended color extraction step, the computer is caused to extract recommended colors 33 from a plurality of selected colors 32 as recommended colors 33 for the color of the selected component 30B, based on the fixed colors 31 of the fixed components 30A and compatibility data 35. According to this configuration, the colors of the components 30 in the target portion 2 of the building 1 are composed of colors that are compatible with each other, so that a harmonious coordination can be provided for the target portion 2 of the building 1.

[0151] <Modification> The above-mentioned embodiments are examples of forms that the coordination system 10 for the building 1, the coordination method for the building 1, and the coordination program for the building 1 may take, and are not intended to limit the forms. The coordination system 10 for the building 1, the coordination method for the building 1, and the coordination program for the building 1 may take forms different from those exemplified in the above-mentioned embodiments. Examples of such forms include forms in which part of the configuration of the embodiment is replaced, changed, or omitted, or forms in which a new configuration is added to the embodiment. Modified examples of the embodiments are shown below.

[0152] In the first embodiment, the recommended color extraction unit 16 extracts selected colors 32 having a compatibility value higher than a predetermined value from among the compatibility values ​​of each pair as the recommended colors 33 for the color of the selected component 30B based on the fixed colors 31 of the fixed component 30A and the compatibility data 35. In contrast to this, the recommended color extraction unit 16 may extract a predetermined number of selected colors 32 in descending order of compatibility value from among the compatibility values ​​of each pair as the recommended colors 33 for the color of the selected component 30B based on the fixed colors 31 of the fixed component 30A and the compatibility data 35.

[0153] 4, the additional compatibility data 36 may include fourth additional compatibility data 36D related to taste. The fourth additional compatibility data 36D includes pairs of the taste of the building model 41 and each of the multiple selection colors 32 of the exterior wall 5, and a compatibility value associated with each pair. The taste of the building model 41 includes a Japanese taste, a Western taste, and a modern taste. According to such fourth additional compatibility data 36D, when a taste is previously associated with the building model 41, a color that matches the taste of the building model 41 can be extracted from the multiple selected colors 32 for the exterior wall 5 for the color of the exterior wall 5. For example, when a Japanese-style building model 41 is selected, the colors that the exterior wall 5 can take are narrowed down from the multiple selected colors 32 for the exterior wall 5 to only colors that match the Japanese taste.

[0154] In the above embodiment, the compatibility data 35 is provided for each paint type of the selection component 30B (exterior wall 5), and the color variations of the fixed color 31 that the fixed component 30A (sash 3 and roof 4) can take are the same regardless of the paint type. However, the color variations of the fixed color 31 that the fixed component 30A can take may be different for each paint type. That is, in the polychromatic compatibility data 35, the multiple fixed colors 31 that the sash 3 and roof 4 can take and the multiple selection colors 32 that the exterior wall 5 can take may each be set as polychromatic colors, and in the monochromatic compatibility data 35, the multiple fixed colors 31 that the sash 3 and roof 4 can take and the multiple selection colors 32 that the exterior wall 5 can take may each be set as monochromatic colors. In this case, for example, the paint type setting unit 18 displays an image of the component 30 with color variations according to the set paint type on the input screen 26 in the second step S2 of FIG. 10. For example, when the paint type is set to a monochrome, the paint type setting unit 18 displays several images on the input screen 26 shown in Figure 5 showing multiple fixed colors 31 for the sash 3 and roof 4 that have color variations corresponding to the monochrome color.

[0155] In the above embodiment, the fixed components 30A and the selection components 30B were selected from the exterior components 30 of the building 1, but if the target part 2 for coordination is the interior, the fixed components 30A and the selection components 30B may be selected from the interior components.
