Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in a building, when a color is arbitrarily selected from a coordinate database for the color of a predetermined component, there is a risk that the color balance may be disrupted in relation to the color of the predetermined component and the colors of other components. In this regard, there is room for improvement in a system for coordinating a building, a method for coordinating a building, and a building coordination program.

Means for Solving the Problems

[0005] (1) The coordinate system of a building for solving the above problems is a coordinate system for coordinating the colors of target parts in a building. Components that make up the target part and have their colors fixed in advance are defined as fixed components, and components that make up the target part and have their colors selected are defined as select components. A storage unit stores compatibility data indicating the compatibility of each set of colors, including each of the multiple types of fixed colors set as the colors that the fixed components can take and each of the multiple types of select colors set as the colors that the select components can take. A fixed color setting unit sets the fixed color of the fixed component by selecting from the multiple types of the fixed colors. A recommended color extraction unit extracts the recommended color from the multiple types of select colors based on the fixed color of the fixed component and the compatibility data as the recommended color for the color of the select component. An output unit outputs the recommended color. The compatibility data includes a set of each of the multiple types of the fixed colors and each of the multiple types of select colors, and a compatibility value associated with each set. According to this configuration, in the target part of the building, the colors of the components are composed of colors with good compatibility with each other, so a harmonious coordination can be provided for the target part of the building.

[0006] (2) In the coordinate system of the building according to (1) above, the recommended color extraction unit extracts, as the recommended color for the color of the select component, a select color with a compatibility value higher than a predetermined value from among the compatibility values of each set based on the fixed color of the fixed component and the compatibility data, or extracts a predetermined number of select colors from among the compatibility values of each set in descending order of the compatibility value as the recommended color. According to this configuration, a color with good compatibility with the color of the fixed component can be accurately selected as the color of the select component.

[0007] (3) In the coordinate system of the building according to the above (1) or (2), for additional components different from the fixed components and the selected components, the recommended color extraction unit extracts, from the multiple types of colors that the additional components can take, a color that is compatible with the recommended color extracted for the selected components as the additional element recommended color of the additional components. According to this configuration, for the additional components, an additional element recommended color that is compatible with the selected components can be selected.

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

[0009] (5) In the coordinate system of the building according to any one of the above (1) to (4), the storage unit further stores the compatibility data between the selection components indicating the compatibility of each set of colors between the multiple types of selection colors that one of the two selection components can take and the multiple types of selection colors that the other of the two selection components can take. The recommended color extraction unit extracts the recommended color based on the fixed color of the fixed component, the compatibility data between the fixed component and the selection component, and the compatibility data between the selection components as the recommended color of the colors of the two selection components. According to this configuration, the recommended color can be selected so that it is compatible with the color of the fixed component and is compatible with each other between the two selection components.

[0010] (6) The method for coordinating a building for solving the above problems is a method for coordinating the color of a target part in a building. The component that constitutes the target part and has a color fixed in advance is defined as a fixed component, and the component that constitutes the target part and has a color selected is defined as a selected component. A preparation step of preparing compatibility data indicating the compatibility of each set of a plurality of fixed colors set as the colors that the fixed component can take and a plurality of selected colors set as the colors that the selected component can take; a fixed color setting step of setting the fixed color of the fixed component by selecting from the plurality of fixed colors; a recommended color extraction step of extracting the recommended color from the plurality of selected colors based on the fixed color of the fixed component and the compatibility data as the recommended color of the color of the selected component; and an output step of outputting the recommended color. The compatibility data includes a set of each of the plurality of fixed colors and each of the plurality of selected colors, and a compatibility value associated with each set. According to this configuration, in the target part of the building, the colors of the components are configured to be colors with good compatibility with each other, so that a harmonious coordination can be provided for the target part of the building.

[0011] (7) In the method for coordinating a building according to (6) above, in the recommended color extraction step, as the recommended color of the color of the selected component, based on the fixed color of the fixed component and the compatibility data, among the compatibility values of each set, the selected color with a compatibility value higher than a predetermined value is extracted as the recommended color, or a predetermined number of selected colors are extracted as the recommended color in descending order of the compatibility values of each set. According to this configuration, a color with good compatibility 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 a building according to (6) or (7) above, in the recommended color extraction step, further, for additional components different from the fixed components and the selected components, from among a plurality of colors that the additional components can take, a color that is compatible with the recommended color extracted for the selected components is extracted as the additional component recommended color for the additional components. According to this configuration, for the additional components, an additional component recommended color that is compatible with the selected components can be selected.

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

[0014] (10) In the method for coordinating a building according to any one of (6) to (9) above, preparation is made of compatibility data between the selected components indicating the compatibility of each set of colors of a plurality of selectable colors that one of the two selected components can take and a plurality of selectable colors that the other of the two selected components can take. In the recommended color extraction step, as the recommended colors of the colors of the two selected components, based on the fixed color of the fixed component, the compatibility data between the fixed component and the selected components, and the compatibility data between the selected components, the recommended colors are extracted. According to this configuration, the recommended colors can be selected so as to be highly compatible with the color of the fixed component and to be compatible with each other between the two selected components.

[0015] (11) The coordinate program for a building that solves the above problems is a coordinate program for a computer to coordinate the color of a target part in a building. The components that make up the target part and have their colors fixed in advance are defined as fixed components, and the components that make up the target part and have their colors selected are defined as selectable components. A reading step of reading compatibility data indicating the compatibility of each set of colors, including each of the multiple types of fixed colors set as the colors that the fixed components can take and each of the multiple types of selectable colors set as the colors that the selectable components can take; a fixed color setting step of setting the fixed color of the fixed components by selecting from the multiple types of the fixed colors; a recommended color extraction step of extracting the recommended color from the multiple types of selectable colors based on the fixed color of the fixed components and the compatibility data as the recommended color for the color of the selectable components; and an output step of outputting the recommended color. The compatibility data includes a set of each of the multiple types of the fixed colors and each of the multiple types of the selectable colors, and a compatibility value associated with each set. According to this configuration, in the target part of the building, the colors of the components are configured to be colors with good compatibility with each other, so that a harmonious coordination can be provided for the target part of the building.

Mode for Carrying Out the Invention

[0018] <First Embodiment> Referring to FIGS. 1 to 10, the coordinate system 10 of the building 1 of the present embodiment will be described. The coordinate system 10 coordinates the color of the target portion 2 in the building 1. Examples of the building 1 to be coordinated include houses, apartment houses, stores, public facilities, hotels, and the like.

[0019] The target portion 2 to be coordinated is the exterior or interior of the building 1. In the description of the present embodiment, the target portion 2 to be coordinated is the exterior of the building 1. The exterior of the building 1 may be only the exterior of the building body, or may be the entire exterior including the building body and the exterior structure. In the present embodiment, the target portion 2 is the entire exterior including the building body and the exterior structure. The building body is a house.

[0020] In one example, the coordinate system 10 is used when renovating the exterior of building 1. Specifically, when the renovation changes the exterior to a different appearance from that of building 1 before the renovation, the coordinate system 10 is used. In the coordinate system 10, after presetting the colors of some components 30 that make up the exterior of building 1, for the other components 30, colors that are compatible with the preset colors are searched for. The coordinate system 10 proposes an exterior appearance with a harmonious color scheme for the entire building 1.

[0021] The exterior of building 1 is determined by the color balance of the components 30 of the exterior of building 1. The components 30 of the exterior of building 1 are the sash 3, the roof 4, the outer wall 5, the eaves 6, the fence 7 as an exterior structure, the planting 8 as an exterior structure, the eaves of the veranda, the front door, and so on. The main elements affecting the exterior are the color of the roof 4, the color of the sash 3, and the color of the outer wall 5. Among these, the colors of the roof 4 and the sash 3 are often maintained as the existing colors. For this reason, in one example, the colors of the roof 4 and the sash 3 are set to the existing colors.

[0022] FIG. 1 shows a conceptual diagram of the coordinate system 10. As shown in FIG. 1, based on the preset colors of the roof 4 and the sash 3 (hereinafter referred to as the colors of the fixed component 30A), the coordinate system 10 uses the compatibility data 35 to search for the color of the outer wall 5 (hereinafter referred to as the color of the selected component 30B) that is compatible with these colors. Then, based on the preset color of the roof 4, the color of the sash 3, and the color of the outer wall 5 that has been found, the coordinate system 10 creates an image diagram of the exterior of building 1 and outputs the image diagram. As a result, the user can grasp the image of building 1 after renovation.

[0023] The coordinate system 10 may be used not only for coordinating the appearance when renovating the building 1, but also for coordinating the appearance of the newly constructed building 1. The coordinate system 10 may be used when a designer considers the appearance of the new building 1. The coordinate system 10 may be used for coordinating the interior decoration of the building 1. Hereinafter, specific examples of the coordinate system 10 will be described. Also, an example of when the coordinate system 10 is used in coordinating the appearance during the renovation of the building 1 will be described.

[0024] [Coordinate system] As shown in FIG. 2, the coordinate 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 coordinate system 10 may further include a building model setting unit 13, a component setting unit 14, an outer wall painting specification setting unit 17, a painting type setting unit 18, an outer wall pattern setting unit 19, and an input unit 21.

[0025] [Fixed components] In the coordinate system 10, the fixed component 30A is defined as follows. The fixed component 30A is a component 30 that constitutes the coordinate target portion 2 and 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 components 30 of the appearance of the building 1. Also, the fixed component 30A may be selected from among the first predetermined components preset among the components 30 of the appearance of the building 1.

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

[0028] [Selectable Component] In the coordinate system 10, the selectable component 30B is defined as follows. The selectable component 30B is a component 30 that constitutes the target part 2 of the coordinate and is a component 30 whose color is selected by the coordinate system 10.

[0029] In the coordinate system 10, the selectable component 30B may be configured to be selectable by the user. The selectable component 30B is selected from the components 30 of the appearance of the building 1. The selectable component 30B may be selected from among the second predetermined components preset among the components 30 of the appearance of the building 1. In one example, the second predetermined component includes the outer wall 5.

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

[0031] In this embodiment, the number of selected components 30B varies according to the type of outer wall painting specification. The coordinate system 10 in this embodiment has two types of outer wall painting specifications. One of the two outer wall painting specifications is a single-color painting, and the other is a two-color painting. In the case of single-color painting, one outer wall 5 that covers the entire outer surface of the building 1 is set as the selected component 30B. In the case of two-color painting, an outer wall 5 that covers a part of the outer surface of the building 1 and an outer wall 5 that covers another part of the outer surface of the building 1 are set as the selected components 30B. For example, in the case of two-color painting, the outer wall 5 on the first floor and the outer wall 5 on the second floor become separate selected components 30B. The outer wall painting specification is set by the outer wall painting specification setting unit 17 based on the user's designation.

[0032] [First Storage Unit] The first storage unit 11 includes semiconductor memories such as RAM (Random Access Memory), ROM (Read Only Memory), and SSD (Solid State Drive), and storage media such as hard disks, optical disks, magnetic disks, and magnetic tapes.

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

[0034] The first storage unit 11 stores the shape data of the target part 2 in the building 1 for each building model 41. In this embodiment, the target part 2 to be coordinated is the appearance of the building 1. Therefore, the first storage unit 11 stores the CAD data of the components 30 that constitute the appearance of the building 1 as the shape data.

[0035] The first storage unit 11 stores, for each building model 41, the type of the outer wall painting specification and the painting information corresponding to the outer wall painting specification. As described above, there are two types of outer wall painting specifications. The first type of the outer wall painting specification is a single-color painting. The second type of the outer wall painting specification is a two-color painting. The first storage unit 11 stores the painting information in association with the specification of the two-color painted outer wall 5 for each building model 41. The painting information is information indicating the first-color area and the second-color area in the building model 41. For example, the first-color area is set as the outer wall area of the first floor part. The second-color area is set as the outer wall area of the second floor part. In another example, the first-color area is set as the outer wall area of the first and second floor parts. The second-color area is set as the loggia wall area.

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

[0037] [Second Storage Unit] The second storage unit 12 includes a storage medium. Examples of the storage medium are the same as the examples of the storage medium given in the description of the first storage unit 11. Each of the first storage unit 11 and the second storage unit 12 may be configured as a part of one storage medium. The second storage unit 12 may be configured by a storage medium of a type different from that of the first storage unit 11. Also, the second storage unit 12 may be configured by a storage medium of the same type as that of 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 one storage unit.

[0038] The second storage unit 12 stores the components 30 of the appearance of the building 1. Specifically, the second storage unit 12 stores the components 30 of the appearance of the building 1 in association with the building model 41. In the present embodiment, the components 30 of the appearance are the roof 4, the outer wall 5, the sash 3, the eaves soffit 6, the fence 7, and the planting 8 as an exterior structure. The components 30 of the appearance may include a rain gutter, a window lattice, a front door, a gate fence, etc. The components 30 of the appearance may be set for each building model 41.

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

[0040] Specifically, the second storage unit 12 stores, for the sash 3 as the fixed component 30A, several fixed colors 31 that the sash 3 can take. Also, the second storage unit 12 stores, for the roof 4 as the fixed component 30A, several fixed colors 31 that the roof 4 can take. Also, the second storage unit 12 stores, for the outer wall 5 as the selectable component 30B, several selectable colors 32 that the outer 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 selectable component 30B and the fixed component 30A. The compatibility data 35 indicates the compatibility of each set of colors between each of the plurality of types of fixed colors 31 set as the colors that the fixed component 30A can take and each of the plurality of types of selectable colors 32 set as the colors that the selectable component 30B can take. Hereinafter, specific examples of the compatibility data 35 will be described.

[0042] [Compatibility Data] The compatibility data 35 includes pairs of each of a plurality of types of fixed colors 31 and each of a plurality of types of selectable colors 32, and compatibility values associated with each pair. The compatibility value indicates the goodness of 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 data in a table format. The data format of the compatibility data 35 may be an array data format.

[0043] Referring to FIG. 3, an example of the compatibility data 35 will be described. 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 outer wall 5A is set to the selectable component 30B. The second outer wall 5B is set to the selectable component 30B.

[0044] In the compatibility data 35, the sash 3 has a plurality of types of fixed colors 31 that can be taken as the color of the sash 3. The roof 4 has a plurality of types of fixed colors 31 that can be taken as the color of the roof 4. The first outer wall 5A has a plurality of types of selectable colors 32 that can be taken as the color of the first outer wall 5A. The second outer wall 5B has a plurality of types of selectable colors 32 that can be taken as the color of the second outer 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 pairs of each of a plurality of types of fixed colors 31 of the sash 3 and each of a plurality of types of selectable colors 32 of the first outer wall 5A, and compatibility values associated with each pair. The second compatibility data 35B includes pairs of each of a plurality of types of fixed colors 31 of the roof 4 and each of a plurality of types of selectable colors 32 of the first outer wall 5A, and compatibility values associated with each pair. The third compatibility data 35C includes pairs of each of a plurality of types of selectable colors 32 of the first outer wall 5A and each of a plurality of types of selectable colors 32 of the second outer wall 5B, and compatibility values associated with each pair.

[0046] In the example of FIG. 3, the compatibility values have four values. In FIG. 3, the compatibility values are indicated by double circles, circles, triangles, and crosses in descending order of good color compatibility. For comparison operations, 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, the double circle is associated with 4. The circle is associated with 3. The triangle is associated with 2. The cross is associated with 1.

[0047] Furthermore, the compatibility data 35 is provided for each painting type of the select component 30B (the outer wall 5 in this embodiment). Examples of the painting types include multicolor and single color. Multicolor is a color composed of overlapping multiple colors. Single color is a color composed of one color. The color variations of the selectable colors 32 that the outer wall 5 can take when the painting type is single color are different from the color variations of the selectable colors 32 that the outer wall 5 can take when the painting type is multicolor. For this reason, the compatibility data 35 is provided for each painting type of the outer wall 5. Note that the color variations of the fixed colors 31 that the fixed component 30A (the sash 3 and the roof 4 in this embodiment) can take are the same regardless of the painting type of the select component 30B.

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

[0049] Note that in the compatibility data 35 for multicolor, the multiple selectable colors 32 that the first outer wall 5A and the second outer wall 5B can take are set as multicolor. In the compatibility data 35 for single color, the multiple selectable colors 32 that the first outer wall 5A and the second outer wall 5B can take are set as single color.

[0050] Whether to use monochromatic compatibility data 35 or multicolored compatibility data 35 is set according to the user's specification via the input unit 21. In this embodiment, a compatibility table that is monochromatic compatibility data 35 and a compatibility table that is multicolored compatibility data 35 are stored in the second storage unit 12, and a compatibility table corresponding to the painting type set by the painting type setting unit 18 based on the user's instruction is used. Note that the compatibility data 35 shown in FIG. 3 is monochromatic compatibility data 35. Illustration of the multicolored compatibility data 35 is omitted.

[0051] In addition to the above-described compatibility data 35, the second storage unit 12 may store other compatibility data. Referring to FIG. 4, other compatibility data (hereinafter, additional compatibility data 36) will be described. The additional compatibility data 36 is data that is referred to when selecting the color of an additional component 30C other than the fixed component 30A among the components 30 of the building 1 (hereinafter, the additional component 30C). For example, after the color of the first outer wall 5A as the selected component 30B is set, the additional compatibility data 36 is referred to 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 a first additional compatibility data 36A, a second additional compatibility data 36B, and a third additional compatibility data 36C.

[0053] The first additional compatibility data 36A includes each set of a plurality of colors of the eaves lining 6 and each of a plurality of selected colors 32 of the first outer wall 5A, and a compatibility value associated with each set. The second additional compatibility data 36B includes each set of a plurality of colors of the fence 7 and each of a plurality of selected colors 32 of the first outer wall 5A, and a compatibility value associated with each set. The third additional compatibility data 36C includes each set of each of the plurality of colors of the planting 8 and each of the plurality of selectable colors 32 of the first outer wall 5A, and the compatibility value associated with each set.

[0054] According to the additional compatibility data 36, when the selectable color 32 of the first outer wall 5A is set, the color of the eaves 6, the color of the fence 7, and the planting 8 with good compatibility with the selectable color 32 of the first outer wall 5A can be selected. In one example, the additional compatibility data 36 is referred to, for example, when changing the color of the additional component 30C after the image diagram of the appearance of the building 1 is completed.

[0055] Referring to FIG. 3, an example of the use of the compatibility data 35 will be described. When the outer wall painting specification is a single-color painting, since the outer wall 5 is of a single color, there is no need to consider the compatibility between the first outer wall 5A and the second outer wall 5B. Therefore, the third compatibility data 35C indicating the compatibility between the first outer wall 5A and the second outer wall 5B is not used. Thus, when the outer wall painting specification is a single-color painting and the sash 3 and the roof 4 are set as the fixed component 30A, the first compatibility data 35A and the second compatibility data 35B are used to extract the recommended color 33 of the first outer wall 5A.

[0056] When the outer wall painting specification is a two-color painting, since the outer wall 5 is painted in two colors, it is necessary to consider the compatibility between the first outer wall 5A and the second outer wall 5B. Therefore, the third compatibility data 35C indicating the compatibility between the first outer wall 5A and the second outer wall 5B is used. Thus, when the outer wall painting specification is a two-color painting and the sash 3 and the roof 4 are set as the fixed component 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 of the first outer wall 5A and the second outer wall 5B.

[0057] [Input section] The input section 21 is a device that receives the user's designation. An example of the input section 21 is a touch panel. Other input sections 21 are a keyboard or a mouse. The input section 21 receives the user's selection regarding the selection items displayed on the display screen of the display device 25.

[0058] FIG. 5 is an example of an input screen 26 displayed on a display device 25 connected to the coordinate system 10.

Then, the recommended color extraction unit 16 sets the selectable color 32 of the first outer wall 5A in each of the extracted sets as the first recommended color 33A with respect to the roof 4.

[0075] Then, the recommended color extraction unit 16 sets the selectable color 32 of the first outer wall 5A that is extracted as the first recommended color 33A with respect to the sash 3 and is also extracted as the first recommended color 33A with respect to the roof 4 as the recommended color 33. In this way, the recommended color extraction unit 16 extracts, as the recommended color 33, a color that is compatible with both the sash 3 and the roof 4.

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

[0077] [Output unit] Referring to FIGS. 8 and 9, the output unit 20 will be described. The output unit 20 outputs an image diagram 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 the present embodiment, the target portion 2 is the exterior appearance of the building 1.

[0078] Specifically, the output unit 20 forms an image diagram of the exterior appearance of the colored building 1 by applying the recommended color 33 to the first outer wall 5A, the fixed color 31 to the roof 4, and the fixed color 31 to the sash 3 with respect to the shape data of the building model 41 selected in advance. The building 1 shown in the image diagram has a first outer wall 5A of the recommended color 33, a sash 3 of the user-specified fixed color 31, and a roof 4 of the user-specified fixed color 31. The output unit 20 outputs the image diagram of the exterior appearance 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 outer wall 5A. FIG. 8 shows the coordinated image diagrams of each of the four recommended colors 33 for the exterior appearance of the building model 41. The user can select one from the four image diagrams for the exterior appearance of the building model 41 by specifying via the input unit 21.

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

[0081] The color change button panel 27 displays the buttons 28 of the components 30 that constitute the appearance of the building 1 and the color selection palette 29 of the colors that each of the components 30 can take.

The components 30 within the color change button panel 27 may include fixed components 30A, selectable components 30B, and additional components 30C. An example of the components 30 within the color change button panel 27 is the sash 3, the roof 4, the outer wall 5, the eaves interior 6, the fence 7, and the planting 8. In the present embodiment, the components 30 within the color change button panel 27 include selectable components 30B and additional components 30C. At the location where the color of the color selection palette 29 is displayed, if the color is a color that is compatible with the color of the first outer wall 5A, a mark 29X indicating a recommendation is attached. The user can select a color with reference to the mark 29X. With the color change button panel 27, the user can further change the color of the component 30 from the image diagram.

[0082] In the building 1, the recommended color 33 of the first outer wall 5A does not match either the user-specified fixed color 31 for the sash 3 or the user-specified fixed color 31 for the roof 4. For this reason, 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 the image diagram of the target portion 2 to a device with a display unit.

[0085] In the second step S2, the painting type setting unit 18 sets the painting type based on the designation of the user via the input unit 21. Specifically, the painting type setting unit 18 sets a multicolor or a single color for the painting type of the outer wall 5. The painting type setting unit 18 prepares a compatibility table of the compatibility data 35 according to the set painting type.

[0086] In the third step S3, the fixed color setting unit 15 sets the fixed color 31 of the sash 3 based on the designation of the user via the input unit 21.

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

[0088] In the fifth step S5, the outer wall painting specification setting unit 17 sets the outer wall painting specification based on the designation of the user via the input unit 21. Specifically, the outer wall painting specification setting unit 17 sets a single-color painting or a two-color painting for the outer wall painting specification. By setting the outer wall painting specification, the setting method of the recommended color 33 of the outer wall 5 executed by the recommended color extraction unit 16 is switched. The setting method of the recommended color 33 of the outer wall 5 in the single-color painting is the above-described method shown in the present embodiment. The setting method of the recommended color 33 of the outer wall 5 in the two-color painting is the method described later shown in the second embodiment.

[0089] In the sixth step S6, the outer wall pattern setting unit 19 sets the outer wall pattern 42 based on the designation of the user via the input unit 21. Note that, as long as there is no contradiction, the processing order of each step may be interchanged for the first step S1 to the sixth step S6.

[0090] In the seventh step S7, the recommended color extraction unit 16 extracts a recommended color 33 for the outer wall 5 based on information on whether it is a single-color coating or a two-color coating, the fixed color 31 of the sash 3, the fixed color 31 of the roof 4, and the compatibility data 35. Further, the recommended color extraction unit 16 extracts, as a color compatible with the recommended color 33 extracted for the outer wall 5 from among a plurality of colors that the additional components 30C such as the eaves soffit 6, the fence 7, and the planting 8 can take, a color as an additional element recommended color 34 based on the additional compatibility data 36.

[0091] In the eighth step S8, the output unit 20 forms an image diagram of the appearance of the building 1 based on the building model 41, the fixed color 31 of the sash 3, the fixed color 31 of the roof 4, the outer wall pattern 42, and the recommended color 33. Then, the output unit 20 outputs the image diagram of the appearance of the building 1 to the display device 25. Also, the output unit 20 causes the display device 25 to display a color selection palette 29 for selecting a color compatible with the recommended color 33 of the outer wall 5 for the eaves soffit 6, the fence 7, and the planting 8.

[0092] [Operations of this Embodiment] The operations of this embodiment will be described. In this coordination system 10, a fixed component 30A whose color is preset and a selection component 30B for which a recommended color 33 is searched are set among the components 30 that constitute the appearance of the building 1. Then, using the compatibility data 35 between the colors that the fixed component 30A can take and the colors that the selection component 30B can take, a color having good compatibility with the fixed component 30A is searched as the recommended color 33 recommended for the selection component 30B. Thereby, a harmonious coordination can be provided for the appearance of the building 1.

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

[0094] (2) The recommended color extraction unit 16 extracts, as the recommended color 33 of the color of the selectable component 30B, the selected color 32 with a compatibility value higher than a predetermined value among the compatibility values of each pair based on the fixed color 31 of the fixed component 30A and the compatibility data 35. Alternatively, the recommended color extraction unit 16 extracts, as the recommended color 33 of the color of the selectable component 30B, a predetermined number of selected colors 32 from the highest compatibility value order among the compatibility values of each pair based on the fixed color 31 of the fixed component 30A and the compatibility data 35. According to this configuration, as the color of the selectable component 30B, a color with good compatibility with the color of the fixed component 30A can be accurately selected. Specifically, "can be accurately selected" means the following. When determining compatibility by the designer's sense, there is variation in the judgment of colors with good compatibility. In contrast, in this coordinate system 10, for the fixed color, the recommended color 33 regarded as having good compatibility does not change for each process.

[0095] (3) The recommended color extraction unit 16 extracts, as an additional element recommended color 34, a color compatible with the recommended color 33 from a plurality of colors that the additional component 30C can take. According to this configuration, for the additional component 30C, an additional element recommended color 34 compatible with the selectable component 30B can be selected.

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

[0107] Specifically, the recommended color extraction unit 16 extracts, as the recommended color 53 of the colors of the two selectable components 30B, the fixed color 31 of the fixed component 30A, the compatibility data 38A between the fixed component 30A and the selectable component 30B, and the compatibility data 38B between the selectable components 30B, and extracts, as the recommended color 53, the selectable color 32 with a compatibility value higher than a predetermined value among the compatibility values of each pair.

[0108] Referring to FIG. 12, a specific example of the procedure for finding the recommended color 53 of the first outer wall 5A and the second outer wall 5B will be described. In this example, the first outer wall 5A and the second outer wall 5B are set as the selectable components 30B.

[0109] [First Step] In the first step, the secondary recommended color 51C of the first outer wall 5A is extracted. The recommended color extraction unit 16 extracts, as the first primary recommended color 51A, the recommended color 53 of the first outer wall 5A with respect to the sash 3 based on the first compatibility data 35A indicating the compatibility between the sash 3 and the first outer wall 5A and the fixed color 31 of the sash 3. More specifically, the recommended color extraction unit 16 extracts a pair having a compatibility value higher than a predetermined value among the compatibility values of each pair of the fixed color 31 of the sash 3 and each of the plurality of selectable colors 32 of the first outer wall 5A. Then, the recommended color extraction unit 16 sets the extracted selectable color 32 of the first outer wall 5A for each pair as the first primary recommended color 51A with respect to the sash 3.

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

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

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

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

[0114] Based on the second compatibility data 35B indicating the compatibility between the roof 4 and the second outer wall 5B and the fixed color 31 of the roof 4, the recommended color extraction unit 16 extracts the recommended color 53 of the second outer wall 5B for the roof 4 as the first recommended color 52B. More specifically, the recommended color extraction unit 16 extracts a set having a compatibility value higher than a predetermined value from among the compatibility values of each set of the fixed color 31 of the roof 4 and the plurality of types of selected colors 32 of the second outer wall 5B. Then, the recommended color extraction unit 16 sets the selected color 32 of the second outer wall 5B of each extracted set as the first recommended color 52B for the roof 4.

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

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

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

[0118] Specifically, the recommended color extraction unit 16 extracts a combination of colors with good compatibility from the recommended values of each set of the four second recommended colors 51C for the first outer wall 5A and the four second recommended colors 52C for the second outer wall 5B, based on the third compatibility data 35C. In this embodiment, a predetermined number or more of recommended colors 53 are extracted. Specifically, as the set of recommended colors 53 for the first outer wall 5A and the second outer wall 5B, a set of the fourth color and the sixth color (hereinafter, set A) and a set of the fifth color and the sixth color (hereinafter, set B) are extracted. The compatibility value of set A is triangular, but excluding set A, there is only one recommended set. Therefore, in this example, two sets are selected.

[0119] [Effects of this Embodiment] The effects of this embodiment will be described. In the coordinate system 10, for the two select components 30B, the recommended color extraction unit 16 extracts the recommended color 53 based on the fixed color 31 of the fixed component 30A, the compatibility data 38A between the fixed component 30A and the select component 30B, and the compatibility data 38B between the select components 30B. According to 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 each other between the two select components 30B.

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

[0122] [Coordinate Method in Single - Color Painting] In the coordinate method, a component 30 that constitutes the target part 2 and whose color is fixed in advance is defined as the fixed component 30A. Also, a component 30 that constitutes the target part 2 and whose color is selected is defined as the select component 30B. For example, the sash 3 and the roof 4 are defined as the fixed component 30A. The outer wall 5 is defined as the select component 30B.

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

[0124] In the preparation step, the shape data of the target part 2 in the building 1 is prepared. Further, the compatibility data 35 is prepared.

[0125] In the coordinate method for single - color painting, the compatibility data 35 between the fixed component 30A and the select component 30B is prepared. The compatibility data 35 indicates the compatibility of each set of colors between a plurality of fixed colors 31 set as the colors that the fixed component 30A can take and a plurality of selectable colors 32 set as the colors that the selectable component 30B can take.

[0126] The compatibility data 35 includes a set of each of the plurality of fixed colors 31 and each of the plurality of selectable colors 32, and a compatibility value associated with each set. Specific examples of the compatibility data 35 are the first compatibility data 35A and the second compatibility data 35B shown in the first embodiment.

[0127] In the fixed color setting step, the fixed color 31 of the fixed component 30A is set by selecting from among the plurality of fixed colors 31.

[0128] In the recommended color extraction step, the recommended color 33 is extracted from among the plurality of selectable colors 32 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 selectable component 30B. Specifically, in the recommended color extraction step, based on the fixed color 31 of the fixed component 30A and the compatibility data 35, among the compatibility values of each set, the selectable color 32 with a compatibility value higher than a predetermined value is extracted as the recommended color 33.

[0129] Alternatively, in the recommended color extraction step, based on the fixed color 31 of the fixed component 30A and the compatibility data 35, a predetermined number of selectable colors 32 may be extracted as the recommended color 33 in descending order of the compatibility values among the compatibility values of each set.

[0130] In the output step, the target portion 2 colored based on the recommended color 33, the fixed color 31, and the shape data of the target portion 2 is output.

The compatibility data 38B indicates the color compatibility of each set of a plurality of selectable colors 32 that one of the two selectable components 30B can take and a plurality of selectable colors 32 that the other selectable component 30B of the two selectable components 30B can take.

[0132] In the coordination method for two-color painting, in the coordination method for single-color painting, the following processing is added. In the recommended color extraction step, based on the fixed color 31 of the fixed component 30A, the compatibility data 38A between the fixed component 30A and the selectable component 30B, and the compatibility data 38B between the selectable components 30B, the recommended color 53 is extracted as the recommended color of the colors of the two selectable components 30B.

[0133] [Effects of the present embodiment] The effects of the present embodiment will be described. (1) The coordination method includes a recommended color extraction step. In the recommended color extraction step, based on the fixed color 31 of the fixed component 30A and the compatibility data 35, the recommended color 33 is extracted from a plurality of selectable colors 32 as the recommended color of the color of the selectable component 30B. According to this configuration, in the target part 2 of the building 1, the colors of the components 30 are composed of colors with good compatibility with each other, so a harmonious coordination can be provided for the target part 2 of the building 1.

[0134] (2) In the recommended color extraction step, based on the fixed color 31 of the fixed component 30A and the compatibility data 35, among the compatibility values of each set, the selectable color 32 with a compatibility value higher than a predetermined value is extracted as the recommended color 33. Alternatively, in the recommended color extraction step, based on the fixed color 31 of the fixed component 30A and the compatibility data 35, among the compatibility values of each set, a predetermined number of selectable colors 32 are extracted as the recommended color 33 in descending order of compatibility value. According to this configuration, a color with good compatibility with the color of the fixed component 30A can be accurately selected as the color of the selectable component 30B.

[0135] (3) In the recommended color extraction process, as the recommended color 53 of the colors of the two selectable components 30B, based on the fixed color 31 of the fixed component 30A, the compatibility data 38A between the fixed component 30A and the selectable component 30B, and the compatibility data 38B between the selectable components 30B, the recommended color 53 is extracted. According to 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 each other between the two selectable components 30B.

[0136] (4) In the recommended color extraction process, from among the multiple colors that the additional component 30C can take, a color that is compatible with the recommended color 33 is extracted as the additional element recommended color 34. According to this configuration, for the additional component 30C, the additional element recommended color 34 that is compatible with the selectable component 30B can be selected.

[0137] (5) The output process outputs an image of the target part 2 colored based on the recommended color 33, the fixed color 31, and the shape data of the target part 2. According to this configuration, an image diagram of the target part 2 can be output.

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

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

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

[0144] The compatibility data 35 includes a set of each of a plurality of fixed colors 31 and a plurality of selection colors 32, and a compatibility value associated with each set.

[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 is caused to extract a recommended color 33 from a plurality of selection colors 32 based on the set fixed color 31 of the fixed component 30A and the compatibility data 35 as the recommended color 33 of the color of the selection component 30B.

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

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

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

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

[0151] <Modification Example> The above embodiment is an exemplification of the forms that the coordinate system 10 of the building 1, the coordinate method of the building 1, and the coordinate program of the building 1 can take, and is not intended to limit the form. The coordinate system 10 of the building 1, the coordinate method of the building 1, and the coordinate program of the building 1 can take forms different from the forms exemplified in the above embodiment. Examples thereof are forms in which a part of the configuration of the embodiment is replaced, changed, or omitted, or forms in which a new configuration is added to the embodiment. Modification examples of the embodiment are shown below.

[0152] ·In the first embodiment, the recommended color extraction unit 16 extracts, as the recommended color 33 of the color of the selection component 30B, the selection color 32 having a compatibility value higher than a predetermined value among the compatibility values of each pair based on the fixed color 31 of the fixed component 30A and the compatibility data 35. On the other hand, the recommended color extraction unit 16 may extract, as the recommended color 33 of the color of the selection component 30B, a predetermined number of selection colors 32 from the highest compatibility value order among the compatibility values of each pair based on the fixed color 31 of the fixed component 30A and the compatibility data 35.

[0153] · As shown in FIG. 4, the additional compatibility data 36 may include fourth additional compatibility data 36D regarding taste.

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 associated with the building model 41 in advance, for the color of the outer wall 5, a color that suits the taste of the building model 41 can be extracted from among the plurality of selectable colors 32 of the outer wall 5. For example, when a Japanese building model 41 is selected, the colors that the outer wall 5 can take are narrowed down to only the colors that suit the Japanese taste from among the plurality of selectable colors 32 of the outer wall 5.

[0154] · In the above embodiment, the compatibility data 35 is provided for each painting type of the selectable component 30B (outer wall 5), and the color variations of the fixed colors 31 that the fixed components 30A (sash 3 and roof 4) can take were the same regardless of the painting type. However, the color variations of the fixed colors 31 that the fixed component 30A can take may be different for each painting type. That is, in the multi-color compatibility data 35, the plurality of fixed colors 31 that the sash 3 and the roof 4 can take and the plurality of selectable colors 32 that the outer wall 5 can take are each set in multi-color, and in the single-color compatibility data 35, the plurality of fixed colors 31 that the sash 3 and the roof 4 can take and the plurality of selectable colors 32 that the outer wall 5 can take may each be set in single-color. In this case, for example, in the second step S2 of FIG. 10, the painting type setting unit 18 displays an image of the component 30 with color variations corresponding to the set painting type on the input screen 26. For example, when the painting type is set to single-color, the painting type setting unit 18 displays several images showing a plurality of fixed colors 31 with color variations corresponding to the single-color for the sash 3 and the roof 4 on the input screen 26 shown in FIG. 5.
