Description

[Technical field]

[0001] One aspect of the present invention relates to a color design support device, method, and program that support the design of color schemes for information transmission media such as guide signs, printed matter, and websites. [Background technology]

[0002] In recent years, visual information transmission technology has become more advanced and diverse, and information is now provided through a variety of color combinations. However, there are individual differences in color vision, and some color schemes may not convey visual information correctly. For example, there are colors that are difficult to distinguish for people with different color vision than the general public or for people whose color vision has deteriorated with age. For this reason, when designing color schemes for information transmission media, it is important to take into account the diversity of people's color vision when designing color schemes.

[0003] Conventionally, the color scheme for an object is determined by a procedure in which, for example, a color scheme is first provisionally set for people with normal color vision, then the provisionally set color scheme is checked to see how it appears to people with color vision different from that of the general public, and any colors that are determined to have a problem with appearance as a result of this check are corrected (see, for example, non-patent document 1). [Prior art documents] [Non-patent literature]

[0004] [Non-Patent Document 1] "Tokyo Metropolitan Government Color Universal Design Guidelines," Tokyo Metropolitan Government Bureau of Social Welfare and Public Health, Department of Life and Welfare, Community Welfare Promotion Division, Internet<URL: https: / / www.fukushi.metro.tokyo.lg.jp / kiban / machizukuri / kanren / color.html> Published in March 2011 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the color scheme method described in Non-Patent Document 1 takes into consideration how people with color vision different from that of normal color vision can correctly recognize information, but does not take into consideration design or beauty.

[0006] In addition, Non-Patent Document 1 also describes another color scheme method, which uses only colors included in a recommended color scheme set. However, this method limits the number of colors that can be used by people with normal color vision, and the flexibility of color schemes is lost, making it difficult to create color schemes that take design and beauty into consideration.

[0007] In general, the design and beauty of a color scheme is an extremely important factor, as it affects the communication of information to both people with color vision deficiencies and those with normal color vision.

[0008] This invention has been made in light of the above-mentioned circumstances, and aims to provide technology that enables highly flexible color arrangements for both those with color vision deficiency and those with normal color vision, thereby ensuring design and beauty and improving information transmission. [Means for solving the problem]

[0009] In order to solve the above problems, a first aspect of a color design support device or support method according to the present invention, when supporting the design of a color scheme for an information transmission medium, acquires reproduced color information of colors distinguishable by the color vision corresponding to each of a plurality of types of color vision and information representing a confusion line. In this state, when a first color vision classified as a color vision deficiency is specified among the color visions, first, a first color distinguishable by the specified first color vision is selected from the reproduced color information corresponding to the first color vision. Next, a second color different from the first color and suitable for a general second color vision is acquired, which is selected by a user based on the confusion line corresponding to the first color vision and including the first color, By replacing the first color with the obtained second color. The first color is corrected.

[0010] According to the first aspect of the present invention, when a first color vision classified as a color vision deficiency is specified as a color vision to be set for a color scheme, a first color suitable for the first color vision is selected. Then, colors on a confusion color line that corresponds to the first color vision and includes the first color are presented to a user, and the first color is corrected based on a second color selected and input by the user that is different from the first color and suitable for a general second color vision. As a result, it is possible to propose a color scheme with excellent information transferability that can be distinguished by a first color vision person classified as a color vision deficiency, and that is easy to attract the attention of a general color vision person.

[0011] A second aspect of the color design support device according to the present invention, when supporting the design of a color scheme for an information transmission medium, obtains reproduction color information of colors distinguishable by the color vision corresponding to each of a plurality of types of color vision and confusion color line information expressed by an xy function formula in an xy chromaticity space, the confusion color line being represented by an xy function formula in the xy chromaticity space. In this state, when a first color vision classified as a color vision deficiency is designated from among the plurality of types of color vision, a first color distinguishable by the designated first color vision is selected based on the reproduction color information corresponding to the first color vision. Next, the xy function formula representing the confusion color line corresponding to the first color vision and including the first color is displayed, and the displayed xy function formula is used to select a first color distinguishable by the designated first color vision. function Based on the formula design The person in charge selects a correction candidate color that is different from the first color and is suitable for general second color vision. The second This allows the input of color 2.

[0012] According to the second aspect of the present invention, a second color that is different from the first color and is adapted to a general second color vision is automatically selected, thereby reducing the burden on the designer in selecting the color. Effect of the Invention

[0013] In other words, according to one aspect of the present invention, it is possible to provide technology that enables highly flexible color arrangements for both people with color vision deficiency and those with normal color vision, thereby ensuring design and beauty and improving information transmission.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0016] [One embodiment] (Configuration example) One embodiment of the present invention uses an information processing device such as a personal computer to assist a color design engineer (also referred to as a user) in designing color schemes for information transmission media such as guide signs and printed matter to be installed at stations or event venues, or for websites.

[0017] 1 and 2 are block diagrams showing an example of the hardware configuration and software configuration of a color design support device TM according to an embodiment of the present invention.

[0018] The color design support device TM is configured, for example, by a general-purpose personal computer used by a designer. The color design support device TM may also be configured by a server computer located on the web or in the cloud.

[0019] The color design support device TM includes a control unit 1 using a hardware processor such as a central processing unit (CPU). A storage unit having a program storage unit 2 and a data storage unit 3, a communication interface (hereinafter, the interface will be referred to as I / F) unit 4, and an input / output I / F unit 5 are connected to the control unit 1 via a bus 6.

[0020] The communication I / F unit 4 transmits and receives information data to and from a site on the Web or cloud (not shown) or to and from another information processing terminal, according to a communication protocol defined by a network including the Internet or an intranet, for example.

[0021] The input / output I / F unit 5 performs input / output processing of input information and display information between the input device 7 and the display device 8. The input device 7 is composed of, for example, a keyboard and a mouse, and is used by a designer to input various requests related to color scheme design, color specification information, and the like to the color design support device TM.

[0022] The display device 8 is composed of a display using, for example, liquid crystal or organic EL (Electro Luminescence) and is used to display color samples of correction candidate colors presented by the color design support device TM in the process of designing a color scheme, and display information of an information transmission medium colored with the corrected color scheme combination.

[0023] The input / output I / F unit 5 may be connected to an external storage medium such as a Universal Serial Bus (USB) memory.

[0024] The program storage unit 2 is, for example, a combination of a non-volatile memory such as a HDD (Hard Disk Drive) or SSD (Solid State Drive) as a storage medium that can be written to and read from at any time, and a non-volatile memory such as a ROM (Read Only Memory), and stores application programs necessary for executing various processes related to one embodiment of the present invention, in addition to middleware such as an OS (Operating System).

[0025] The data storage unit 3 is, for example, a combination of a non-volatile memory such as an HDD or SSD as a storage medium that can be written to and read from at any time, and a volatile memory such as a RAM (Random Access Memory).The storage area includes a color vision-specific reproduction color storage unit 31, a color confusion line information storage unit 32, and a color scheme combination information storage unit 33.

[0026] The color vision-specific reproduction color storage unit 31 is used to store reproducible colors created for each color vision. The color vision-specific reproduction colors are the overall image of colors recognized by a person with color vision classified as color vision deficiency (hereinafter also referred to as a person with color vision deficiency) when he / she sees all hues, and are assumed to be an infinite number of colors. The color vision-specific reproduction colors are expressed as a combination of specific distinguishable colors, but may also be expressed as a combination of different confusion color lines distinguishable by a person with color vision deficiency.

[0027] The confusion line information storage unit 32 stores a program for creating confusion line information that has been created in advance for each type of color vision. The information representing the confusion line for each type of color vision is, for example, an xy function that indicates the relationship between x (red) and Y (green) on the CIE (International Commission on Illumination) xy chromaticity diagram.

[0028] The color scheme combination information storage unit 33 is used to store color scheme combination information generated by the color scheme design support process by the control unit 1.

[0029] The control unit 1 includes, as processing units according to one embodiment of the present invention, a color vision-specific reproduction color acquisition processing unit 11, a color confusion line information acquisition processing unit 12, a color vision type designation information acquisition processing unit 13, a color scheme combination provisional setting processing unit 14, a color scheme combination correction processing unit 15, and a color scheme combination information output processing unit 16.

[0030] The processing units 11 to 16 are all realized by causing a hardware processor of the control unit 1 to execute an application program stored in the program storage unit 2. Note that a part or all of the processing units 11 to 17 may be realized using hardware such as an LSI (Large Scale Integration) or an ASIC (Application Specific Integrated Circuit).

[0031] The color vision-specific reproduction color acquisition processing unit 11 acquires color vision-specific reproduction colors via the communication I / F unit 4, for example, from an information site that manages color design guide information, and stores the acquired color vision-specific reproduction colors in the color vision-specific reproduction color storage unit 31 by linking them to color vision type information.

[0032] The confusion color line information acquisition processing unit 12 acquires a confusion color line information creation program, which has been created in advance for each type of color vision, from the information site via the communication I / F unit 4, and stores the acquired confusion color line information creation program in the confusion color line information storage unit 32. Note that if the confusion color line information creation program has been stored in advance in the confusion color line information storage unit 32, it is not necessary to acquire the program.

[0033] The color vision type designation information acquisition processing unit 13 receives information designating a type of color vision classified as, for example, color vision deficiency, input by a designer at the input device 7, via the input / output I / F unit 5. The color vision type designation information acquisition processing unit 13 may also have a function of acquiring information representing the information transmission medium before coloring.

[0034] The color combination provisional setting processing unit 14 sets color combinations for color vision deficiency persons, reads color vision-specific reproduction colors corresponding to the type of color vision specified by the color vision type designation information from the color vision-specific reproduction color storage unit 31, selects color combination candidates that can be distinguished by color vision deficiency persons based on the read color vision-specific reproduction colors, and enables a designer who performs color design to provisionally set the color combinations. Note that the color combination provisional setting processing unit 14 may autonomously set the color combination candidates without presenting the color combination candidates to the designer.

[0035] The color combination correction processing unit 15 corrects the color combination provisionally set for people with color vision deficiency by the color combination provisional setting processing unit 14 so that it is suitable for people with normal color vision who do not fall under the category of color vision deficiency (hereinafter also referred to as normal color vision), and stores information representing the color combination after the correction in the color combination information storage unit 33. An example of the color combination correction processing will be described in the operation example.

[0036] The color combination information output processing unit 16 reads out color combination information from the color combination information storage unit 33, generates display information of an information transmission medium colored using the read color combination, and outputs the generated display information from the input / output I / F unit 5 to the display device 8 for display.

[0037] (Example of operation) Next, an example of the operation of the color design support device TM configured as above will be described.

[0038] Here, the following three types of color vision deficiencies are targeted: protanope (hereinafter referred to as protanope), which is a type of color vision deficiency caused by mutations in the red (L) cones (hereafter referred to as protanope), deuteranope (hereinafter referred to as D-type color vision), which is a type of color vision deficiency caused by mutations in the green (M) cones (hereafter referred to as D-type color vision), and tritanope (hereinafter referred to as T-type color vision), which is a type of color vision deficiency caused by mutations in the blue (S) cones. As an example, we will explain the case where we propose color combinations that are suitable for both protanope and people with general color vision.

[0039] FIG. 3 is a flowchart showing an example of the processing procedure and processing contents of the color scheme design support processing executed by the control unit 1 of the color design support device TM.

[0040] (1) Acquisition of reproduced colors for different color vision For example, assume that a person in charge of color scheme design inputs a color scheme assistance request via the input device 7 .

[0041] When the control unit 1 of the color design support device TM detects the color scheme support request in step S10, first in step S11, under the control of the color vision-specific reproduction color acquisition processing unit 11, it accesses, for example, an information site that manages color design information, and acquires information representing reproduction colors for each color vision from the information site via the communication I / F unit 4. Then, it associates the acquired information representing reproduction colors for each color vision with color vision type information and stores it in the color vision-specific reproduction color storage unit 31.

[0042] Figure 4 shows an example of the characteristics of color vision possessed by people with normal color vision, people with P-type color vision, and people with D-type color vision. As shown in this example, the combinations of "blue" and "purple," "light blue" and "pink," "gray" and "light green," "dark green" and "brown," "dark red" and "burnt brown," "red" and "green," and "yellow" and "yellowish green" are distinguishable by people with normal color vision, but are difficult to distinguish by people with P-type color vision and people with D-type color vision.

[0043] In other words, people with P-type color vision and D-type color vision have difficulty distinguishing between “green” and “red” colors, as shown in Figure 5, but can distinguish between “blue” and “green” colors.

[0044] Considering the characteristics of color vision of P-type and D-type color vision people, a boundary line TH1 is set between the "blue" system and the "green" system, and a color combination is selected from the color areas on either side of this boundary line TH1, and the selected color combination is used as a color scheme for P-type or D-type color vision people. TH0 indicates the center of the area of ​​colors that are difficult for P-type and D-type color vision people to distinguish.

[0045] In the above description, the case where color vision-specific reproduction colors corresponding to all types of color vision are obtained is taken as an example, but it is also possible to specify the color vision of the design target in advance and obtain only the color vision-specific reproduction colors corresponding to the specified type of color vision. Also, instead of obtaining the color vision-specific reproduction colors from an information site each time the color scheme support process is executed, it is also possible to continuously use the color vision-specific reproduction colors that have been stored once.

[0046] (2) Acquisition of a program for creating color confusion line information Next, in step S12, the control unit 1 of the color design support device TM, under the control of the confusion color line information acquisition processing unit 12, acquires a previously prepared confusion color line information creation program via the communication I / F unit 4, and stores the acquired confusion color line information creation program in the confusion color line information storage unit 32. Note that if the confusion color line information creation program has been previously stored in the confusion color line information storage unit 32, the acquisition process is omitted.

[0047] Figure 6 shows the CIExy chromaticity diagram, which shows a standard chromaticity distribution, and an outline of the confusion lines corresponding to P-type color vision, D-type color vision, and T-type color vision based on this chromaticity diagram. In this diagram, each straight line in the two-dimensional chromaticity xy space is a confusion line, and each of these confusion lines can be expressed by an xy function.

[0048] Although colors on the confusion line look different to a person with normal color vision, they look confused as the same color to a person with dichromatic color vision, such as a person with P-type color vision or a person with D-type color vision. In other words, when a color that can be distinguished for a person with P-type color vision or a person with D-type color vision is selected, it is possible to present a variety of colors to a person with normal color vision, while maintaining the color distinguishability of a person with P-type color vision or a person with D-type color vision, by replacing the selected color with any color on the confusion line that includes the selected color. The color design support device TM performs the color scheme correction process described later, focusing on this characteristic.

[0049] Figures 7 and 8 show specific examples of color confusion lines corresponding to protanopia and deuteranomalous color vision, respectively. Note that protanopia has difficulty recognizing the color "red" with a wavelength of 670 nm or more, as shown in Figure 7, due to a mutation in the red (L) cone. For this reason, red colors of 670 nm or more are excluded from the color confusion lines.

[0050] (3) Temporary color combinations For example, when designing a color combination that takes into consideration people with color vision deficiencies for an information transmission medium such as a homepage, the designer inputs the type of color vision for which the design is to be performed and template data for the information transmission medium before coloring via the input device 7.

[0051] In response to this, when the control unit 1 of the color design support device TM detects the above-mentioned color vision type designation input in step S13 under the control of the color vision type designation information acquisition processing unit 13, in step S14, under the control of the color vision type designation information acquisition processing unit 13, first, reads out color vision-specific reproduction colors corresponding to the color vision designated by the above-mentioned color vision type designation information from the color vision type designation color storage unit 31. Then, the color vision combination temporary setting processing unit 14 selects and provisionally sets a color combination that can be distinguished by a person having the above-mentioned designated color vision, based on the read out color vision-specific reproduction colors.

[0052] For example, if P-type color vision is specified as the type of color vision for which the color scheme is being designed, the color scheme combination provisional setting processing unit 14 reads out the color vision-specific reproduction colors prepared for P-type color vision, and presents the read out color vision-specific reproduction colors to the person being designed, thereby enabling the person being designed to select a color scheme combination.

[0053] Figure 9 shows an example of a color combination selected for P-type color vision in the form of a color sample. In this example, "blue," "light blue," "brown," "dark brown," and "yellow" are selected. All of these colors are color combinations that P-type color vision people can distinguish.

[0054] (4) Correcting color combinations Next, the control unit 1 of the color design support device TM, under the control of the color combination correction processing unit 15, executes a process for correcting the provisionally set color combination as follows.

[0055] That is, in step S15, the color combination correction processing unit 15 first calculates, for each of the colors constituting the provisionally set color combination, a color confusion line that corresponds to the color vision type designated by the designer and includes the provisionally set color, by using a color confusion line information creating program stored in the color confusion line information storage unit 32. Then, on the calculated color confusion line, a plurality of colors different from the provisionally set color are selected as correction candidate colors.

[0056] More specifically, the color combination correction processing unit 15 first uses the above-mentioned color confusion line information creating program to display the color confusion line information calculated using the x and y values ​​in the xy chromaticity space of the provisionally set color as parameters on the display device 8 in step S16, thereby presenting it to the designer in charge of color design. The designer in charge of color design selects correction candidate colors within a range that can be converted using the xy function that represents the above-mentioned color confusion line information, taking into consideration the design, and inputs the selected correction candidate colors. In this way, the designer can select correction candidate colors from all colors defined on the color confusion line.

[0057] When presenting the correction candidate colors, the color combination correction processing unit 15 displays the correction candidate colors using, for example, a slider so that the designer can select any color from an infinite number of candidate colors while checking the effect. Note that instead of using a slider, display sample information of a medium in which the correction candidate colors are reflected may be generated and presented.

[0058] When the designer specifies the correction candidate color, the color combination correction processing unit 15 receives, in step S17, the specification information of the correction candidate color specified and input via the input / output I / F unit 5. Then, the color combination correction processing unit 15 corrects the provisionally set color based on the specified and input correction candidate color. More specifically, the provisionally set color is replaced with the specified and input correction candidate color.

[0059] For example, when correcting the color combination provisionally set for P-type color vision shown in Figure 9, the colors are corrected to, for example, "blue" → "purple," "light blue" → "pink," "brown" → "green," "dark brown" → "red," and "yellow" → "yellowish green" so that they will be more noticeable to people with normal color vision. Figure 10 shows an example of the above corrections applied to the color scheme of the character "Color."

[0060] In step S18, the color scheme combination correction processing unit 15 then stores information representing the color scheme combination after the correction in the color scheme combination information storage unit 33. The color scheme combination correction processing unit 15 executes the above-described correction process for each of the colors constituting the provisionally set color scheme.

[0061] (5) Output of color combination information Finally, in step S19, under the control of the color combination information output processing unit 16, the control unit 1 of the color design support device TM reads out information representing the result of the color combination from the color combination information storage unit 33, and outputs the display information of an information transmission medium such as a homepage, which has been colored based on the read color combination information, from the input / output I / F unit 5 to the display device 8 for display.

[0062] The control unit 1 of the color design support device TM repeatedly executes a series of steps S13 to S19 of the color scheme design support process every time a new color vision type is input until a request to end the design support process is input. Then, when it detects in step S20 that a request to end the design support process has been input, the process ends.

[0063] (effect) As described above, in one embodiment, first, the color vision-specific reproduction colors corresponding to the type of color vision and the color confusion line information creation program prepared in advance for each color vision, for example, a program using an xy function formula in the xy chromaticity space, are acquired and stored in the color vision-specific reproduction color storage unit 31 and the color confusion line information storage unit 32 in the data storage unit 3, respectively. Then, when the type of color vision to be designed is specified and input in this state, the designer is first made to select a color combination for a person with color vision deficiency based on the color vision-specific reproduction colors corresponding to the type of color vision, and the selected color combination is provisionally set. Next, based on the xy function formula of the color confusion line information creation program corresponding to the type of color vision and including the provisionally set color, correction candidate colors suitable for a person with normal color vision are displayed on the display device 8 so that multiple selections can be made from an infinite number of colors while changing parameters. Then, based on the correction candidate colors selected by the designer, the provisionally set color combination is corrected, and the display information of the information transmission medium colored with the corrected color combination is displayed on the display device 8.

[0064] Therefore, according to one embodiment, it is possible to propose to designers color combinations that are highly designable even for people with P-type or D-type color vision, which are classified as color vision deficiencies, and that are also easily eye-catching for people with normal color vision, in other words, have excellent information-transmitting properties.

[0065] [Other embodiments] (1) In one embodiment, color samples of all colors on the color confusion line excluding the colors provisionally set for people with color vision deficiency are presented to allow the designer to select and specify any color. However, multiple correction candidate colors may be selected from the color confusion line and presented to the designer, and information may be obtained indicating the color selected by the designer from the multiple presented colors.

[0066] (2) In the embodiment, the case where the correction candidate color is selected based on the xy function formula representing the color confusion line has been described as an example. However, the present invention is not limited to this. For example, data representing a plurality of color samples included on the color confusion line may be stored in advance in the color confusion line information storage unit 32, and a desired color may be selected as the correction candidate color from among the plurality of stored color samples.

[0067] (3) In one embodiment, a series of color combination design processes are performed each time color vision type information is input. However, for example, each time the color combination design process is completed, the correction results of the color combination, for example, the number of selections or selection frequency, may be stored in the data storage unit 3 as correction history information for each color vision. When the next design process is performed, a recommendation level may be set for each previously selected color according to the number of selections or selection frequency based on the correction history information corresponding to the target color vision, and correction candidate colors may be selected and presented according to this recommendation level.

[0068] (4) In one embodiment, the reproduction colors for each color vision are acquired and stored, but it is also possible to acquire reproduction colors for each color vision created arbitrarily by a designer. Also, the color design support device TM may independently create and store color samples for color universal design based on information that indicates the characteristics of how colors appear for each color vision.

[0069] (5) In one embodiment, colors on the confusion color line that correspond to a first color vision and include a first color are presented to a user in charge of color scheme design, and the user selects and inputs a second color that is different from the first color and is suitable for a general second color vision from among the colors on the confusion color line presented to the user.

[0070] However, the present invention is not limited to this, and the control unit 1 may perform a process of automatically selecting a second color that is different from the first color and is suitable for general second color vision based on the xy function formula of the color confusion line. In this case, for example, colors selected by the user in the past may be saved as a selection history, and the color that has been selected most frequently in the past may be automatically selected based on this selection history. In this way, it is possible to select a color that meets the user's desire while reducing the burden on the user required for color selection. The above-mentioned automatic correction color selection process can also be realized by the control unit 1 causing the processor to execute a program.

[0071] (6) In addition, various modifications can be made to the type and functional configuration of the color design support device, its processing procedures and processing contents, types of color vision and the configuration of the corresponding color scheme recommendation information, etc., without departing from the spirit and scope of the present invention.

[0072] Although the embodiment of the present invention has been described in detail above, the above description is merely an example of the present invention in every respect. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. In other words, in implementing the present invention, specific configurations according to the embodiment may be appropriately adopted.

[0073] In short, this invention is not limited to the above-mentioned embodiment as it is, and in the implementation stage, the components can be modified and embodied without departing from the gist of the invention. In addition, various inventions can be formed by appropriately combining multiple components disclosed in the above-mentioned embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, components from different embodiments may be appropriately combined.

A color design support device that supports color arrangements for information transmission media, comprising: a first processing unit that acquires information on reproduced colors and information on color confusion lines that correspond to each of a plurality of types of color vision and are distinguishable by the color vision; a second processing unit that, when a first color vision classified as a color vision deficiency is designated among the plurality of types of color vision, selects a first color that can be distinguished by the designated first color vision based on the reproduced color information corresponding to the first color vision; a third processing unit that acquires a second color that is different from the first color and is adapted to a general second color vision, the second color being selected by a user based on the confusion color line that corresponds to the first color vision and includes the first color, and corrects the first color by replacing the first color with the acquired second color; A color design support device comprising:

2. A color design support device that supports color arrangements for information transmission media, comprising: a first processing unit that acquires reproduction color information of colors distinguishable by the color vision corresponding to each of a plurality of types of color vision and confusion color line information that represents a confusion color line by an xy function formula in an xy chromaticity space; a second processing unit that, when a first color vision classified as a color vision deficiency is designated among the plurality of types of color vision, selects a first color that can be distinguished by the designated first color vision based on the reproduced color information corresponding to the first color vision; a third processing unit that displays the xy function formula representing the confusion color line corresponding to the first color vision and including the first color, and receives an input of a second color selected by a designer as a correction candidate color different from the first color and adapted to a general second color vision based on the displayed xy function formula; A color design support device comprising:

3. 2. The color design support device according to claim 1, wherein the third processing unit displays a plurality of candidate colors for the second color included in the confusion color line, accepts a selection designation operation by the user for the displayed plurality of candidate colors, and determines the candidate color selected by the selection designation operation as the second color.

4. 4. The color design support device according to claim 3, wherein the third processing unit generates and displays display sample information of the information transmission medium colored by selectively using a plurality of the candidate colors.

5. 4. The color design support device according to claim 3, wherein the third processing unit manages, as correction history information, the number or frequency at which each of the plurality of candidate colors has been determined as the second color, and each time the first color vision is specified, sets a recommendation level according to the number or frequency at which the color has been determined as the second color based on the correction history information, and selects and presents the second color from among the plurality of candidate colors in accordance with this recommendation level.

6. A color design support method in which an information processing device executes a process for supporting a color scheme for an information transmission medium, comprising: obtaining information on reproduced colors and confusion lines of colors distinguishable by a plurality of types of color vision; a step of selecting a first color distinguishable by the first color vision, which is classified as a color vision abnormality, from among the plurality of types of color vision, based on the reproduction color information corresponding to the first color vision; obtaining a second color different from the first color and adapted to a general second color vision, selected by a user based on the confusion line corresponding to the first color vision and including the first color, and correcting the first color by replacing the first color with the obtained second color; A color design support method comprising:

7. 2. A program for causing a processor included in the color design support device to execute processes executed by the first processing unit, the second processing unit, and the third processing unit included in the color design support device according to claim 1.
