[Embodiment]
[1. About the outline of the information providing device]
First, with reference to FIG. 1, an example of a process executed by an information providing device, which is an example of a determination device, will be described. FIG. 1 is a diagram showing an example of a determination process executed by the information providing device according to the embodiment. In the example shown in FIG. 1, an example of a process of determining the color to be given to the content to be created by the user based on the word specified by the user is described.

The information providing device 10 is an information processing device that executes a determination process described below, and is realized by, for example, a server device, a cloud system, or the like. For example, the information providing device 10 can communicate with the terminal device 100 via a predetermined network N (see, for example, FIG. 2) such as the Internet. The information providing device 10 may be able to communicate with any number of terminal devices 100.

The terminal device 100 is realized by various information processing devices such as smart devices such as smartphones and tablets, and PCs (Personal Computers). For example, the terminal device 100 has a function of displaying various information and a function of accepting input of various information from the user. For example, when the terminal device 100 accesses the information providing device 10, the terminal device 100 accepts the distribution of the reception content C10 for receiving the indication of a word and the designation of an image from the user. In such a case, the terminal device 100 displays the reception content C10 on the screen and accepts the designation of a word or an image from the user. Then, the terminal device 100 provides the received word or image to the information providing device 10.

[1-1. About the color given to the content]
Here, various colors are given to the content provided to each user, and such colors give an impression to the user (that is, the atmosphere of the content). It is a factor that fosters. For example, a website with a cool image may mainly use cool colors such as blue, and a website with a warm image may mainly use warm colors such as orange. be. In addition to content provided via the Internet (so-called web content), for example, GUI (Graphical User Interface) content with various colors is displayed on the operation screen of a smartphone or PC. Therefore, various colors are given to such contents according to the atmosphere.

In this way, the colors given to each content are considered to have a great influence on the atmosphere created by the content. However, it can be difficult to give the content a color that creates the desired atmosphere. For example, the impression that the content gives to the user and the atmosphere of the content are determined, but it is necessary to have a great deal of experience as to what color should be given to the content to create such an atmosphere. ..

[1-2. About decision processing]
Here, the information providing device 10 assists in creating content having an impression and atmosphere desired by the user by executing the following determination process. First, the information providing device 10 acquires a word indicating an atmosphere to be given to the content to be generated. Then, the information providing device 10 determines the color to be given to the content based on the received word. For example, the information providing device 10 acquires a word and an image corresponding to the word, and determines a color to be given to the content based on the color included in the image and the word corresponding to the image. For example, the information providing device 10 generates a color corresponding to the atmosphere indicated by the word corresponding to the image from the color included in the image, and the generated color is used as a color to be given to the content.

Hereinafter, an example of the flow of processing executed by the information providing apparatus 10 will be described with reference to FIG. For example, the terminal device 100 receives a set of a word indicating the atmosphere of the content and the image corresponding to the word as color information (step S1). For example, the information providing device 10 displays the reception content C10 for accepting a set of a word indicating the atmosphere of the content and an image corresponding to the word.

For example, such reception content C10 has a plurality of input content ICs 11 to IC13, and receives a set of a word and an image via each of the input content ICs 11 to IC13. In the following description, a set of a word and an image may be described as a "column". For example, the input content IC 13 includes a word input content IC 131 that accepts word input, an image input content IC 132 that accepts image input, and a slide bar IC 133 that receives weights indicating how important the column corresponding to the input content IC 13 is. Have.

Through such an input content IC 13, the user registers a word indicating the atmosphere of the content and an image corresponding to the word. For example, when the user selects the word input content IC 131, the terminal device 100 displays a plurality of word candidates indicating the atmosphere of the content. For example, the terminal device 100 displays as a candidate a word set for each set of color and saturation in the PCCS (Practical Color Co-ordinate System).

For example, in PCCS, a set of saturation and lightness called a PCCS tone is set. For example, in PCCS, a first set such as "white (W)", "gray (Gy)", and "black (Bk)" is set as a set having the same saturation but different lightness. ing. Further, in PCCS, "Pale tone (p)", "Light grayish tone (lgt)", and "Grayish tone (g)" are used as a set having higher saturation than the first set and different brightness. , And a second set, such as "dark grayish tone (dkg)".

Further, in PCCS, "light tone (lt)", "soft tone (sf)", "dull tone (d)" and "dull tone (d)" are set as a set having higher saturation than the second set and different brightness. A third set such as "dark tone (dk)" is set. Further, in PCCS, "bright tone (b)", "strong tone (s)", and "deep tone (dp)" are used as sets having higher saturation than the third set and different brightness ranges. A fourth set is set. Further, in PCCS, a fifth set such as "vivid tone (v)" having the highest saturation is set.

Then, in the PCCS, a word indicating an atmosphere created by the colors contained in each PCCS tone is set for each PCCS tone (see, for example, Non-Patent Document 1). For example, "white (W)" has words such as "clean", "cold", and "fresh", and "soft tone (sf)" has "soft" and "gentle". , "Vague" and other words are registered in advance.

When the user selects the word input content IC 131, the terminal device 100 displays a plurality of words associated with each PCCS tone as options in a pull-down list format. Then, the terminal device 100 uses a word selected by the user from the list as a word indicating the atmosphere of the content.

Subsequently, the terminal device 100 accepts the input of the image corresponding to the word input by the user via the image input content IC 132. More specifically, the terminal device 100 accepts the input of an image whose color matches the atmosphere indicated by the selected word in the word input content IC 131. For example, when the user selects the word "bright" in the word input content IC 131, the user drags and drops the image # 4 having the impression that the color is "bright" to the image input content IC 132.

Further, the user similarly inputs a set of a word and an image in the input contents IC 11 and IC 12. For example, the user selects the word "cold" in the input content IC 11 and inputs the image # 1 and the image # 2 which have the impression that the color is "cold". As described above, the acceptance content C10 may accept a set of a word and a plurality of images whose colors indicate the atmosphere of the word. Further, for example, the user selects the word "quiet" in the input content IC 12, and inputs the image # 3 having the impression that the color is "quiet".

In addition, the user operates the slide bar to specify how important the input columns in the input contents IC 11 to IC 13 are. For example, the user operates the slide bar of each input content so as to place less importance on the column in the input content IC 11, moderately emphasize the column in the input content IC 12, and emphasize the column in the input content IC 13.

As a result of such user input, the terminal device 100 acquires a plurality of columns and the degree to which the columns are emphasized, that is, a weighting coefficient. In such a case, the terminal device 100 transmits the information of each column and the weighting factor as color information to the information providing device 10 (step S2). As a result, the information providing device 10 acquires a plurality of pairs of the word and the image of the color having the atmosphere indicated by the word thereafter, and acquires a weighting coefficient indicating the weighting corresponding to the atmosphere indicated by each word.

Then, the information providing device 10 determines the color to be given to the content based on the acquired word. More specifically, the information providing device 10 determines a plurality of colors to be given to the content based on the received words. For example, the information providing device 10 is a color given to a text or the like in the content, and is arranged in a first color (hereinafter, referred to as “main color”), a button or the like which is the main color of the design, and tightens the whole. A second color to be a color (hereinafter referred to as "accent color") and a third color to be used for a frame, a background, etc. of the content (hereinafter referred to as "base color") are determined.

More specifically, the information providing device 10 determines each candidate of the main color, the accent color, and the base color for each column. Then, the information providing device 10 determines the main color from the candidates for the main color of each column, determines the accent color from the candidates for the accent color of each column, and determines the base color from the candidates for the base color of each column. For example, the information providing device 10 determines the color obtained by synthesizing the candidate of the main color of each column by the weighting coefficient of each column received from the user as the main color. Further, the information providing device 10 also determines the accent color and the base color by synthesizing the candidates of each column by the weighting coefficient.

That is, the information providing device 10 determines a color candidate to be given to the content for each word, and determines as a color to give a color obtained by synthesizing the determined plurality of color candidates based on the information indicating the weighting to the content. do. For example, the information providing device 10 determines a plurality of color candidates to be given to the content for each word, and indicates weighting of the plurality of color candidates for each purpose of use. The color synthesized based on the information is determined as the color to be given to the content.

Hereinafter, a process in which the information providing device 10 determines each color will be described. In the following description, the column that received the input via the input content IC 11 is the first column, the column that received the input via the input content IC 12 is the second column, and the column that received the input via the input content IC 13. Is referred to as a third column. First, the information providing device 10 extracts a color group from one or a plurality of images included in each column (step S3). For example, the information providing device 10 extracts a plurality of colors included in the image # 1 and the image # 2 as a color group from the image # 1 and the image # 2 in the first column.

To give a more specific example, the information providing device 10 performs image color reduction from image # 1 and image # 2 by using a median cut method. The information providing device 10 may adopt an arbitrary color reduction algorithm such as a quantization method or a k-means method. Further, the information providing device 10 may perform color reduction for each of the image # 1 and the image # 2. For example, all the colors included in the image # 1 and the image # 2 are specified, and each of the specified colors is specified. Color reduction may be performed by a median cut method based on the number of applied pixels. Then, the information providing device 10 performs color reduction until the number of colors reaches a predetermined number (for example, 8 colors), and extracts the colors after the color reduction as the color group # 1 of the first column. Further, the information providing device 10 extracts the color group # 2 of the second column and the color group # 3 of the third column by the same processing.

Subsequently, the information providing device 10 determines a representative color and a non-representative color based on the colors included in the color group (step S4). For example, the information providing device 10 sets a plurality of classes C1 to C7 having different hues, and specifies a class to which the hue of each color included in the color group # 1 belongs. In the example shown in step S4 of FIG. 1, the class to which the hue of each color belongs is indicated by an arrow. Then, for example, as shown in step S4 of FIG. 1, when the most colors belong to the class C2, the information providing device 10 uses the hue corresponding to the class C2 as the hue of the representative color. For example, the information providing device 10 calculates an average value of colors corresponding to class C2 (that is, an average value of HSV values) for each of hue, saturation, and lightness, and represents a color composed of the calculated values. The color.

In the example shown in FIG. 1, the information providing device 10 sets a plurality of classes C1 to C7 having different hues, and the hue of the class to which the most colors belong is set as the hue of the representative color. It is not limited to this. For example, when the colors in the image are held in RGB (Red Green Blue) format, the information providing device 10 converts each color included in the color group into a conical HSV (Hue Saturation Value) value. Subsequently, the information providing device 10 divides the hue circle in the HSV color space into a plurality of regions (for example, 12), and identifies the region to which the hue of each color included in the color group belongs among the divided regions. do. At this time, among the colors included in the color group, the colors whose saturation is out of the predetermined range may be excluded from the processing target. Subsequently, the information providing device 10 has the most hues of the colors. A region is specified, and the average value of the HSV values of the colors corresponding to the specified region is calculated as the HSV value of the representative color.

Subsequently, the information providing device 10 generates a main color in which the lightness and saturation of the representative color are adjusted according to the words (step S5). That is, the information providing device 10 determines as the hue of the first color that gives the content a hue similar to the most of the colors contained in the image among the plurality of hues, and makes the word corresponding to the image. Based on this, at least one of the saturation and the lightness of the color to be given to the content is determined.

For example, the information providing device 10 changes the lightness and saturation according to the word "cold" in the first column while maintaining the hue of the representative color determined from the images # 1 and the image # 2 in the first column. do. For example, the information providing device 10 identifies the PCCS tone “white (W)” corresponding to the word “cold”, and specifies the lightness and saturation corresponding to the specified PCCS tone “white (W)”. Then, the information providing device 10 determines the color changed to the specified lightness and saturation of the lightness and saturation of the representative color as the main color # 1 of the first column. As described above, the information providing device 10 determines the color having the saturation or the saturation corresponding to the acquired word as the color to be given to the content.

Further, the information providing device 10 generates a base color in which the lightness and saturation of the least used color among the colors included in the color group # 1 are adjusted (step S6). For example, among the colors included in the color group # 1, the information providing device 10 is a color that is not adjacent to the main color # 1 on the hue circle, and the color similar to the image # 1 and the image # 2 is most used. Identify colors that are not. Then, the information providing device 10 uses a color in which the saturation and the lightness of the specified color are increased by a predetermined ratio as the base color # 1. That is, the information providing device 10 contains the hue of the color contained in the image # 1 and the image # 2 in the smallest proportion, and the degree of similarity to the first color is lower than a predetermined threshold value. It is determined as the hue of the third color to be given to. The information providing device 10 may determine the base color # 1 based on the lightness and saturation of the PCCS tone corresponding to the word "cold" in the column # 1.

Further, the information providing device 10 determines a color having a complementary color relationship with the main color as an accent color (step S7). That is, the information providing device 10 gives the content a hue having a hue most different from that of the first color among the colors included in the image # 1 and the image # 2, or a complementary color of the first color. Determined as a color. For example, when the color group # 1 includes a color whose hue is located on the opposite side of the main color # 1 on the color wheel, the information providing device 10 uses such a color as an accent color. On the other hand, when the color group # 1 does not include the color to be the accent color # 1, the information providing device 10 calculates the complementary color of the main color # 1 and sets the calculated complementary color as the accent color # 1. ..

Then, the information providing device 10 synthesizes the colors of each column based on the weighting coefficient (step S8). For example, the information providing apparatus 10 executes the processes of steps S3 to S7 described above for each column, so that the main color # 1, the base color # 1, the accent color # 1, and the second column of the first column The main color # 2, the base color # 2, and the accent color # 2, and the main color # 3, the base color # 3, and the accent color # 3 of the third column are generated.

Subsequently, the information providing device 10 specifies a coefficient # 1 which is a weighting coefficient of the first column, a coefficient # 2 which is a weighting coefficient of the second column, and a coefficient # 3 which is a weighting coefficient of the third column. For example, when the left end of each slide bar is 0 and the right end is 1, the information providing device 10 specifies a value of 0 or more and 1 or less according to the position of each slide bar as a coefficient # 1 to a coefficient # 3. Then, the information providing device 10 uses the RGB value of the main color # 1 plus the coefficient # 1, the RGB value of the main color # 2 plus the coefficient # 2, and the RGB value of the main color # 3. The sum of the integrated value of the coefficient # 3 is divided by the sum of the coefficient # 1, the coefficient # 2, and the coefficient # 3, and the value is calculated as the final RGB value of the main color.

The information providing device 10 may calculate the final HSV value of the main color by using the HSV values of the main colors # 1 to # 3. Further, the information providing device 10 determines the final base color from the base colors # 1 to # 3 by executing the same process, and determines the final accent color from the accent colors # 1 to # 3. decide.

Then, the information providing device 10 provides the user with a color palette including the final main color, the final base, and the final accent color as the color to be given to the content (step S9). For example, the information providing device 10 generates a predetermined content CP having a region with a main color, a base color, and an accent color, and distributes the generated content to the terminal device 100. As a result, the information providing device 10 can display the color palette (step S10).

[1-3. Conditions for determining color]
In the above-mentioned example, the information providing device 10 determines the main color, and determines the base color and the accent color in consideration of the relationship with the main color. Here, the information providing device 10 may determine the base color and the accent color so as to satisfy an arbitrary relationship as the relationship with the main color.

For example, the information providing device 10 may determine each color so that the main color, the base color, and the accent color have a so-called color universal design. That is, the information providing device 10 may determine each color so that the main color, the base color, and the accent color are considered for a user whose color appearance is different from that of a general user.

For example, the information providing device 10 determines the main color by the same processing as described above. Subsequently, the information providing device 10 selects a color other than the color that is not adjacent to the main color and is likely to be recognized as the same color as the main color in Color Universal Design as the base color.

Further, the information providing device 10 identifies the complementary color of the main color, and determines whether or not there is a high possibility that the specified complementary color is recognized as the same color as the main color or the base color. Then, when the information providing device 10 is unlikely to be recognized as having the same color as the main color or the base color, the complementary color is selected as the accent color. On the other hand, when there is a high possibility that the specified complementary color is recognized as the same color as the main color or the base color, the information providing device 10 gradually changes the hue of the complementary color on the color wheel in the direction opposite to the base color. While changing to, it is judged whether or not there is a high possibility that the color is recognized as the same as the main color or the base color, and the color that is judged to be less likely to be recognized as the same color is adopted as the accent color. You may.

Further, the information providing device 10 may make the main color, the base color, and the accent color similar to the colors included in the predetermined color scheme considering the color universal design. That is, the information providing device 10 may determine the main color, the base color, and the accent color so as to satisfy a predetermined condition according to the color universal design.

Further, the information providing device 10 may determine the base color and the main color based on the conditions according to the legibility when the text of the main color is superimposed on the base color. For example, the information providing device 10 determines the visibility in a state where the text of the main color is superimposed on the background of the base color, and when the visibility is below a predetermined threshold value, the saturation of the base color or the main color or You may adjust the brightness.

[1-4. About real-time processing]
Further, the information providing device 10 determines the main color, base color, and accent color of each column (hereinafter, referred to as "color palette"), and generates a final color palette from the determined color palette of each column. did. Here, the information providing device 10 may execute such a process in real time and provide it to the user.

For example, the terminal device 100 displays the content CP together with the received content C10. In such a state, each time the terminal device 100 accepts a word change, an image change, or a slide bar operation, the terminal device 100 transmits the changed word, image, and slide bar information to the information providing device 10. In such a case, the information providing device 10 may redetermine the final color palette from the changed word, image, and slide bar status, and display the determined color palette on the terminal device 100. By such processing, the information providing device 10 can propose colors in real time according to the operation of the user, so that usability can be improved.

[1-5. About the column]
In the above example, the information providing device 10 has acquired a word and an image corresponding to the word for three columns. However, the embodiments are not limited to this. For example, when the information providing device 10 acquires a word and an image for one column, the color palette determined from the acquired word and the image may be used as the final color palette. Further, the information providing device 10 acquires a word and an image corresponding to the word for four or more columns, determines a color palette for each column, and synthesizes the determined color palette to obtain a final color palette. May be generated.

[1-6. Correspondence between language and color]
In the above example, the information providing device 10 has the same hue as the color extracted from the image, and corresponds to the word by adopting the lightness and saturation of the PCCS tone corresponding to the word selected by the user. I decided the color to do. However, the embodiments are not limited to this.

For example, words such as "red," "blue," and "yellow" can be associated with hue. Further, the red hue can be associated with a word such as "warm", and the bluish hue can be associated with a word such as "cold". In addition, bluish hues may give the impression of "cool", yellowish hues may give the impression of "happy", and purple hues may give the impression of "rich". There is.

Therefore, the information providing device 10 may determine the hue of the color given to the content based on the word input by the user. Such determination of hue may be realized, for example, on a rule basis, or may be based on various models.

For example, the information providing device 10 is used for models such as SVM (Support Vector Machine), DNN (Deep Neural Network), CNN (Convolutional Neural Network), RNN (Recurrent Neural Network), and LSTM (Long short-term memory). Learn the relationship between a word and the hue corresponding to the word. For example, the information providing device 10 acquires a hue and a word indicating an atmosphere that many users have for the hue based on various information posted on cloud sourcing or a network. Then, the information providing device 10 causes the model to learn the set of the acquired word and the hue as correct answer data.

Further, the information providing device 10 receives a word indicating the atmosphere of the content from the user and a word indicating the atmosphere of the hue instead of the image. In such a case, the information providing device 10 inputs a word indicating the atmosphere of the hue into the model, and the hue output by the model is used as the hue of the color to be given to the content. Then, the information providing device 10 may determine the saturation and lightness of the color to be given to the content based on the word indicating the atmosphere. Further, the information providing device 10 may extract a color corresponding to a word whose hue corresponds to the image from the colors included in the image, and determine the color of the main color from the extracted colors.

It should be noted that the impression of a certain color may differ depending on the language used by the user. Therefore, the information providing device 10 may determine the color to give different colors to the content for each language. For example, the information providing device 10 may associate a different word for each language with each PCCS tone. To give a more specific example, the information providing device 10 associates the word "plain" with "grayish tone (g)", while the English word "plain" corresponding to "plain" is "plain". Instead of "grayish tone (g)", for example, it may be associated with "gray (Gy)" or "dark grayish tone (dkg)".

That is, the information providing device 10 can localize the color to be output according to the input language by changing the relationship between the word and the lightness and the saturation for each language. The information providing device 10 may change the relationship between the word and the hue for each language.

Further, the "corresponding word" is a user for a color in which the tone indicated by the associated "tone information" and the corresponding word, that is, the saturation and the lightness indicated by the associated "tone" are adopted. It is a word that shows the impression of. Further, the "brightness information" is information indicating the brightness. Further, the "saturation information" is information indicating the saturation.

For example, in the example shown in FIG. 3, the tone information "white", the corresponding word "neat, cold, fresh", the brightness information "brightness # 1", and the saturation information "saturation # 1" are registered in association with each other. Has been done. Such information is a tone in which the tone indicated by the tone information "white" corresponds to the corresponding word "neat, cold, fresh", and the brightness and saturation information "color" indicated by the brightness information "brightness # 1". It indicates that the tone is composed of the saturation indicated by "degree # 1".

In addition to the corresponding words shown in FIG. 3, any corresponding word may be associated with each tone. Further, in the example shown in FIG. 3, conceptual values such as "brightness # 1" and "saturation # 1" are described, but in reality, numerical values indicating the lightness and saturation are registered.

The control unit 40 is a controller, and for example, various programs stored in a storage device inside the information providing device 10 by a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) are RAM or the like. Is realized by executing as a work area. Further, the control unit 40 is a controller, and may be realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

As shown in FIG. 2, the control unit 40 includes an acquisition unit 41, an extraction unit 42, a determination unit 43, and a provision unit 44.

The acquisition unit 41 acquires a word indicating an atmosphere to be given to the content to be generated. For example, the acquisition unit 41 acquires a set of a word and an image input by the user via the terminal device 100. More specifically, the acquisition unit 41 acquires a word indicating an atmosphere to be given to the content from the words set for each set of color and saturation in PCCS. Further, the acquisition unit 41 acquires a plurality of words indicating the atmosphere given to the content and information indicating the weighting corresponding to each atmosphere. That is, the acquisition unit 41 acquires the weighting coefficient input via the slide bar for each column.

The extraction unit 42 extracts a color group from the colors included in the image. For example, the extraction unit 42 specifies the colors contained in the image for each column, and reduces the colors contained in the image to a predetermined number by the median cut method. Then, the extraction unit 42 notifies the determination unit 43 of the colors reduced to a predetermined number as a color group.

The determination unit 43 determines the color to be given to the content based on the received word. More specifically, the determination unit 43 determines a plurality of colors to be given to the content based on the colors included in the image and the words corresponding to the images. For example, the determination unit 43 generates a color corresponding to the atmosphere indicated by the word corresponding to the image from the color included in the image, and makes the generated color a color to be given to the content. Further, the determination unit 43 determines the hue of the color to be given to the content based on the color contained in the image, and at least one of the saturation or the lightness of the color to be given to the content based on the word corresponding to the image. Decide one.

For example, the determination unit 43 receives the color group extracted by the extraction unit 42 from the image. Then, the determination unit 43 uses the hue of the color similar to the most colors among the colors included in the received color group as the hue of the main color. For example, the determination unit 43 divides the color wheel into a plurality of ranges and specifies the range to which each color included in the color group belongs. Subsequently, the determination unit 43 identifies the range of hues to which the most colors belong, and identifies the colors belonging to the specified range among the colors included in the color group. Then, the determination unit 43 specifies the average value of the specified colors as the representative color, and sets the hue of the specified representative color as the hue of the main color. That is, the determination unit 43 determines the color having the saturation or lightness corresponding to the acquired word as the color to be given to the content.

Subsequently, the determination unit 43 refers to the color database 31 and identifies the word corresponding to the image and the tone corresponding to it. Then, the determination unit 43 determines the main color by setting the saturation and lightness of the determined tone as the saturation and lightness of the main color.

Further, the determination unit 43 determines as a hue having a hue most different from that of the main color among the colors included in the image, or as an accent color for imparting a complementary color of the main color to the content. For example, the determination unit 43 determines whether or not a color included in a predetermined region facing the main color on the color wheel exists among the colors included in the color group extracted from the image, and if the color is present. If it is determined, that color is used as the accent color. On the other hand, when the color included in the predetermined region facing the main color does not exist in the color group, the determination unit 43 calculates the complementary color of the main color and uses the calculated complementary color as the accent color.

Further, the determination unit 43 imparts to the content a hue of a color having the smallest proportion of the colors contained in the image and having a degree of similarity to the main color lower than a predetermined threshold. Determined as the hue of. For example, the determination unit 43 determines the hue of each color contained in the image, in which the hue is separated from the hue of the main color by a predetermined threshold value or more and the ratio (for example, the number of bits) used is smaller. Identify. Then, the determination unit 43 uses a color in which the saturation and lightness of the specified color are set to a predetermined saturation and lightness as the base color.

The determination unit 43 may determine the base color based on the saturation and the lightness corresponding to the word corresponding to the image. Further, when determining each color, the determination unit 43 may determine a plurality of colors corresponding to Color Universal Design.

Further, the determination unit 43 determines the main color, the base color, and the accent color as candidates for each column. Then, the determination unit 43 determines a plurality of determined candidates as colors to be given to the content by synthesizing the colors based on the information indicating the weighting. For example, the determination unit 43 determines a plurality of color candidates to be given to the content, each having a different purpose of use, for each word, and information indicating weighting of the plurality of color candidates for each purpose of use. The color synthesized based on is determined as the color to be given to the content.

For example, the determination unit 43 synthesizes the main color of the first column, the main color of the second column, and the main color of the third column based on the first coefficient to the third coefficient according to the position of the slide bar. Calculate the color. Similarly, the determination unit 43 calculates the base color obtained by synthesizing the base color of each column based on the first coefficient to the third coefficient, and synthesizes the accent color of each column based on the first coefficient to the third coefficient. Calculate the accent color.

The providing unit 44 provides the user with a predetermined content to which the determined color is given. For example, the providing unit 44 generates a content CP in which the main color, the base color, and the accent color are arranged, and transmits the generated content CP to the terminal device 100.
