Description

Technical Field

[0001] The present application relates to the technical field of color matching processing of products, and in particular to a color matching processing method, device, storage medium and processor. Background Art

[0002] When users use a certain product, they usually encounter multiple legends. In order to present the data intuitively, each legend will have its own fill color, which makes it convenient for users to obtain the content referred to by the legend based on the color. There are two implementation methods in the existing technology: the first method is similar to the Microsoft and WPS chart practices, which fixes the colors of the first to sixth legends as the first group, and the colors of the seventh to twelfth legends as the second group. The second group of colors keeps the color system unchanged on the basis of the first group of colors, and adjusts the brightness. When the thirteenth legend appears, the first and second groups of colors are cycled. The second method is similar to the Chartcube chart practice, which sets a limited number of colors. When the legend exceeds the set limited value, a random color is selected from the set colors as the fill color of the excess legend.

[0003] Both of the above methods result in duplicate legend colors within the chart, meaning that different legends are represented by the same color. Legend colors are part of visualization, and their distinct colors help users easily identify the content they refer to. If multiple identical colors appear repeatedly within a chart, users cannot quickly locate their desired content by focusing solely on the color, significantly reducing the chart's visualization capabilities and making it less efficient for users to find content within the chart by color.

[0046] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0048] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0049] According to an embodiment of the present application, a color matching method is provided.

[0050] Figure 1This is a flow chart of the color matching method according to an embodiment of the present application. Figure 1 As shown, the method includes the following steps:

[0051] Step S101 : determining a plurality of initial legends pre-configured in a target product and the color of each initial legend.

[0052] For example, the target product is a chart, which includes six legends. These six legends are pre-configured with colors. In this application, the pre-configured legends are used as the initial legends. It should be noted that the method of pre-configuring the colors of the legends can be user-defined or pre-configured by the background according to color matching rules.

[0053] It should be noted that the above-mentioned legends can be various types of legends, such as: line charts, column charts, pie charts, bar charts, area charts, etc.

[0054] Step S102 , when it is detected that a new target legend is added to the target product, the colors of two initial legends are selected from the multiple initial legends in the target product to obtain color one and color two.

[0055] For example, if a chart includes six legends, namely Legend 1, Legend 2, Legend 3, Legend 4, Legend 5, and Legend 6, select Legend 1 and Legend 6, set the color of Legend 1 as Color 1, and the color of Legend 6 as Color 2. Alternatively, select Legend 1 and Legend 2, set the color of Legend 1 as Color 1, and the color of Legend 2 as Color 2. That is, select two adjacent initial legends from multiple initial legends in the chart, and set the colors of the two adjacent initial legends as Color 1 and Color 2.

[0056] Step S103 : determining a target color according to the first color and the second color, wherein the target color is an intermediate color between the two initial legend colors.

[0057] It should be noted that the hue value of the intermediate color is between the hue value of color one and the hue value of color two.

[0058] Step S104: Rendering a target legend in the target product using a target color.

[0059] Since the determined target color is the middle color between the colors of the two initial legends, and there is a gap between the middle color and the color of the initial legend, it will not be indistinguishable due to similar color arrangement, thereby avoiding the situation where the color of the newly added legend configuration is repeated or similar to the color of the initial legend in the target product, causing color confusion. Therefore, the target color (middle color) obtained by the above scheme is used to automatically render the color of the newly added legend in the product, thereby improving the efficiency of legend color generation. In addition, when users search for legends in the target product, they can quickly search and distinguish based on color, thereby achieving the effect of improving the efficiency of searching for content by color in the product.

[0060] Optionally, in the color matching processing method provided in the embodiment of the present application, determining the target color based on the color one and the color two includes: converting the color one and the color two to color space one, obtaining color parameter one corresponding to the color one in the color space one, and color parameter two corresponding to the color two in the color space, and determining multiple asymptotic colors between the color one and the color two based on the color parameter one and the color parameter two; and determining the target color from the multiple asymptotic colors.

[0061] It should be noted that the color space 1 described above can convert color 1 and color 2 into computer-recognizable values, that is, color parameter 1 and color parameter 2 are computer-recognizable values. For example, the color space can be an LCH color space, an RGB color space, an HSV color space, etc.

[0062] Through the above solution, it is possible to define how to determine the target color based on color one and color two, thereby ensuring the accuracy of determining the target color.

[0063] Optionally, in the color matching processing method provided in the embodiment of the present application, determining multiple asymptotic colors between the color one and the color two based on the color parameter one and the color parameter two includes: determining multiple candidate asymptotic colors between the color one and the color two using an arithmetic progression calculation method based on the color parameter one and the color parameter two; correcting the multiple candidate asymptotic colors using the interpolation of the color parameter one and the interpolation of the color parameter one; converting the corrected multiple candidate asymptotic colors to color space two; and using the converted multiple candidate asymptotic colors as the multiple asymptotic colors between the color one and the color two.

[0064] It should be noted that, the corrected multiple candidate asymptotic colors are converted through the above color space, and the converted candidate asymptotic colors include hue values, so that the target color is subsequently selected from the multiple candidate asymptotic colors based on the hue values.

[0065] Through the above scheme, it is possible to define how to determine multiple asymptotic colors between the color one and the color two based on the color parameter one and the color parameter two, thereby ensuring the accuracy of determining the asymptotic colors and further ensuring the accuracy of determining the target color.

[0066] Optionally, in the color matching processing method provided in the embodiment of the present application, determining the target color based on color one and color two includes: converting color one and color two to the LCH color space to obtain the lightness, chroma, and hue angle of color one and the lightness, chroma, and hue angle of color two; determining multiple asymptotic colors between color one and color two based on the lightness, chroma, and hue angle of color one and the lightness, chroma, and hue angle of color two; and determining the target color from the multiple asymptotic colors.

[0067] For example, the chart includes 6 legends, namely Legend 1, Legend 2, Legend 3, Legend 4, Legend 5 and Legend 6. Select Legend 1 and Legend 2, and set the color of Legend 1 as Color 1 and the color of Legend 2 as Color 2. Figure 2 As shown, the RGB values ​​of color one and color two are input into the conversion tool, and color one and color two are converted into the LCH color space to obtain the lightness, chroma, and hue angle of color one and the lightness, chroma, and hue angle of color two, thereby determining multiple asymptotic colors (for example, 4 asymptotic colors) between color one and color two based on the lightness, chroma, and hue angle of color one and the lightness, chroma, and hue angle of color two, and selecting one asymptotic color from the multiple asymptotic colors as the target color.

[0068] In the above solution, how to determine the target color based on color one and color two is further defined, thereby ensuring the accuracy of determining the target color.

[0069] Optionally, in the color matching processing method provided in the embodiment of the present application, determining multiple asymptotic colors between color one and color two based on the lightness, chroma, hue angle of color one and the lightness, chroma, hue angle of color two includes: using an arithmetic progression to calculate the lightness, chroma, hue angle of color one and the lightness, chroma, hue angle of color two to determine multiple candidate asymptotic colors between color one and color two; correcting the multiple candidate asymptotic colors by interpolating the three values ​​of lightness, chroma, and hue angle of color one and the three values ​​of lightness, chroma, and hue angle of color two; converting the corrected multiple candidate asymptotic colors to the HSL color space; and using the converted multiple candidate asymptotic colors as the multiple asymptotic colors between color one and color two.

[0070] Since the multiple candidate asymptotic colors between color one and color two are determined by using an arithmetic progression calculation method, there may be multiple candidate asymptotic colors that are not suitable colors. In order to ensure the accuracy of the colors, after the multiple candidate asymptotic colors are determined, the multiple candidate asymptotic colors are corrected by interpolating the three values ​​of the lightness, chroma, and hue angle of color one and the lightness, chroma, and hue angle of color two, thereby ensuring the accuracy of the corrected multiple candidate asymptotic colors. Then, the corrected multiple candidate asymptotic colors are converted to the HSL color space. The hue value of the converted color one is 152, the saturation is 177, and the brightness is 138. The hue value of the converted color two is 111, the saturation is 182, and the brightness is 109. There are four candidate asymptotic colors after conversion, namely asymptotic color 1 (hue value is 145, saturation is 151, and brightness is 126), asymptotic color 2 (hue value is 137, saturation is 152, and brightness is 114), asymptotic color 3 (hue value is 128, saturation is 153, and brightness is 102), and asymptotic color 4 (hue value is 111, saturation is 182, and brightness is 109). The converted multiple candidate asymptotic colors are used as multiple asymptotic colors between color one and color two, as shown in FIG. Figure 3 shown.

[0071] Optionally, in the color matching processing method provided in an embodiment of the present application, determining the target color from multiple progressive colors includes: determining the color of the previous legend adjacent to the target legend in the target product to obtain color three; comparing each progressive color with color three to determine the target color from multiple progressive colors.

[0072] For example, the target product includes six legends: Legend 1, Legend 2, Legend 3, Legend 4, Legend 5, and Legend 6. The previous legend in the target product adjacent to the target legend is Legend 6. Multiple gradient colors are compared to Legend 6 to accurately determine the target color for rendering the target legend from multiple gradient colors. This solution avoids color confusion caused by duplicate or similar colors between the newly added legend and the adjacent legend.

[0073] Optionally, in the color matching processing method provided in an embodiment of the present application, comparing the hue value in each asymptotic color with the hue value in color three to determine the target color from multiple asymptotic colors includes: comparing the hue value in each asymptotic color with the hue value in color three to select a candidate target color from multiple asymptotic colors; judging whether the difference between the hue value of the candidate target color and the hue value in the color of each initial legend is greater than a second preset value; if the difference between the hue value of the candidate target color and the hue value in the color of each initial legend is greater than the second preset value, then using the candidate target color as the target color.

[0074] For example, a chart includes six legends, namely Legend 1, Legend 2, Legend 3, Legend 4, Legend 5, and Legend 6. The previous legend in the chart adjacent to the target legend is Legend 6, and the hue value of Legend 6 is 120. The hue values ​​of Gradient Color 1, Gradient Color 2, Gradient Color 3, and Gradient Color 4 are compared with the hue value of Legend 6 to select a candidate target color from the multiple gradient colors. For example, Gradient Color 1 is selected as the candidate target color, and then it is determined whether the difference in hue value between Gradient Color 1 and the color of each initial legend is greater than 10. For example, if it is determined that the difference in hue value between Gradient Color 1 and the color of each initial legend is greater than 10, Gradient Color 1 is selected as the target color and used to render the newly added target legend. Through the above scheme, the target color is accurately determined from the multiple gradient colors and used to render the newly added target legend, thereby avoiding the situation where the color configured for the target legend overlaps with the color of the initial legends in the chart.

[0075] For example, Figure 4 As shown in the following example, when Legend 7 is added to the chart, the color of Legend 7 is automatically rendered as the target color, that is, the color of Legend 7 is set to the midpoint between the colors of Legend 1 and Legend 2. It should be noted that when multiple legends are added, for example, Legend 8, Legend 9, Legend 12, Legend 13, and so on, the color of Legend 8 is set to the midpoint between the colors of Legend 2 and Legend 3, the color of Legend 12 is set to the midpoint between the colors of Legend 1 and Legend 6, the color of Legend 13 is set to the midpoint between the colors of Legend 7 and Legend 8, and so on.

[0076] Optionally, in the color matching processing method provided in the embodiment of the present application, comparing the hue value in each asymptotic color with the hue value in color three to select a candidate target color from multiple asymptotic colors includes: determining whether the difference between the hue value in each asymptotic color and the hue value in color three is greater than a first preset value; and selecting the asymptotic color whose hue value difference with the hue value in color three is greater than the first preset value as a candidate target color.

[0077] For example, a chart includes six legends, namely Legend 1, Legend 2, Legend 3, Legend 4, Legend 5, and Legend 6. The previous legend adjacent to the target legend in the chart is Legend 6, and the hue value of Legend 6 is 120. The hue values ​​in asymptotic color 1, asymptotic color 2, asymptotic color 3, and asymptotic color 4 are compared with the hue value of Legend 6. For example, the first preset value is 10 and the second preset value is 10. It is determined whether the difference between the hue value in each asymptotic color and the hue value in color three is greater than 10. If the difference between the hue value in asymptotic color 1 and the hue value in color three is greater than 10, asymptotic color 1 is selected as a candidate target color. Through the above scheme, a candidate target color can be accurately obtained from multiple asymptotic colors based on adjacent legends.

[0078] Optionally, in the color matching processing method provided in an embodiment of the present application, if there are multiple candidate target colors, determining whether the difference between the hue value of the candidate target color and the hue value in the color of each initial legend is greater than a second preset value includes: determining whether the difference between the hue value of each candidate target color and the hue value in the color of each initial legend is greater than the second preset value.

[0079] In addition, the method also includes: when there are multiple candidate target colors whose hue values ​​have a difference greater than a second preset value from the hue value in the color of each initial legend, the candidate target color with the largest difference between the hue value in the multiple candidate target colors and the hue value in the color of each initial legend is used as the target color; or, when there is no candidate target color whose hue value has a difference greater than the second preset value from the hue value in the color of each initial legend, the candidate target color with the largest difference between the hue value in the multiple candidate target colors and the hue value in the color of each initial legend is used as the target color.

[0080] For example, if it is determined that the difference between the hue value of asymptotic color 1 and asymptotic color 2 and color three is greater than 10, asymptotic color 1 and asymptotic color 2 are used as candidate target colors, and then it is determined whether the difference between the hue value of asymptotic color 1 and asymptotic color 2 and the color of each initial legend is greater than 10 (a second preset value). For example, if it is determined that the difference between the hue value of asymptotic color 1 and the color of each initial legend is greater than 10, asymptotic color 1 is used as the target color, and the newly added target legend is rendered using asymptotic color 1. Since the difference between the hue value of asymptotic color 2 and the color of each initial legend is not greater than 10, asymptotic color 2 is determined to be a similar visual color to the initial legend, and asymptotic color 2 is deleted.

[0081] If the difference between the hue value of asymptotic color 1 and asymptotic color 2 and the color of each initial legend is greater than a second preset value (for example, the second preset value is 10), the difference between the hue value of asymptotic color 1 and the color of each initial legend is 18, and the difference between the hue value of asymptotic color 2 and the color of each initial legend is 15, asymptotic color 1 is used as the target color, that is, the candidate target color with the largest difference between the hue value and the hue value of the color of each initial legend among multiple candidate target colors is used as the target color.

[0082] If the difference between the hue value of asymptotic color 1 and asymptotic color 2 and the color of each initial legend is not greater than a second preset value (for example, the second preset value is 20), the difference between the hue value of asymptotic color 1 and the color of each initial legend is 18, and the difference between the hue value of asymptotic color 2 and the color of each initial legend is 15, asymptotic color 1 is used as the target color, that is, the candidate target color with the largest difference between the hue value of multiple candidate target colors and the hue value of the color of each initial legend is used as the target color.

[0083] Through the above scheme, when there are multiple target colors that meet the conditions or there is no target color, the candidate target color with the largest difference in hue value from the color in each initial legend is used as the target color, thereby ensuring that the target color can be determined from multiple candidate target colors.

[0084] Optionally, in the color matching processing method provided in the embodiment of the present application, after determining whether the difference between the hue value in each asymptotic color and the hue value in color three is greater than a first preset value, the method further includes: if there is no asymptotic color whose hue value difference with the hue value in color three is greater than the first preset value, then the asymptotic color with the largest difference between the hue value in multiple asymptotic colors and the hue value in color three is selected as a candidate target color.

[0085] For example, the difference between the hue value of progressive color 1 and color three is 18, the difference between the hue value of progressive color 2 and color three is 13, the difference between the hue value of progressive color 3 and color three is 10, the difference between the hue value of progressive color 1 and color three is 8, and the differences between the hue values ​​of progressive color 1, progressive color 2, progressive color 3, and progressive color 4 and color three are all no greater than 20 (a first preset value), that is, there is no progressive color whose hue value difference with the hue value in color three is greater than the first preset value. In this case, progressive color 1 is selected as the candidate target color, that is, the progressive color with the largest difference between the hue value of multiple progressive colors and the hue value in color three is selected as the candidate target color.

[0086] Through the above scheme, when there is no candidate target color, the asymptotic color with the largest difference between the hue value of the multiple asymptotic colors and the hue value of color three is used as the candidate target color, thereby ensuring that the candidate target color can be determined from the multiple asymptotic colors.

[0087] Optionally, in the color matching processing method provided in the embodiment of the present application, after determining whether the difference between the hue value in each asymptotic color and the hue value in color three is greater than a first preset value, the method further includes: if there is an asymptotic color among multiple asymptotic colors whose hue value difference with the hue value in color three is less than or equal to the first preset value, and there is an asymptotic color whose hue value difference with the hue value in color three is greater than the first preset value; the asymptotic color whose hue value difference with the hue value in color three is less than or equal to the first preset value is determined as a similar visual color of color three, and the similar visual color is deleted; the asymptotic color whose hue value difference with the hue value in color three is greater than the first preset value is determined as a non-similar visual color of color three.

[0088] For example, multiple asymptotic colors are asymptotic color 1, asymptotic color 2, asymptotic color 3, and asymptotic color 4. The difference between the hue value of asymptotic color 1 and asymptotic color 2 and the hue value in color three is greater than a first preset value, and the difference between the hue value of asymptotic color 3 and asymptotic color 4 and the hue value in color three is less than or equal to a first preset value; asymptotic color 1 and asymptotic color 2 are determined as non-similar visual colors of color three, asymptotic color 3 and asymptotic color 4 are determined as similar visual colors of color three, and asymptotic colors 3 and 4 are deleted. It should be noted that similar visual colors indicate that the difference in hue value between the colors of the legends is less than the preset difference, thereby giving the user the impression that the colors of the legends are similar in perspective. Similar visual colors indicate that the difference in hue value between the colors of the legends is greater than or equal to the preset difference, thereby giving the user the impression that the colors of the legends are not similar in perspective.

[0089] Through the above scheme, it is possible to distinguish whether the asymptotic color is a similar visual color of color three or a non-similar visual color, and delete the asymptotic color of the similar visual color to reduce the occupied memory space and avoid resource waste.

[0090] Optionally, in the color matching processing method provided in the embodiment of the present application, after determining whether the difference between the hue value of the candidate target color and the hue value in the color of each initial legend is greater than a second preset value, the method further includes: if there is a candidate target color among multiple candidate target colors whose hue value difference between the hue value and the hue value in the color of each initial legend is greater than the second preset value, and there is a candidate target color whose hue value difference between the hue value and the hue value in the color of each initial legend is less than or equal to the second preset value; determine the candidate target color whose hue value difference between the hue value and the hue value in the color of each initial legend is less than or equal to the second preset value as a similar visual color of the initial legend, and delete the similar visual color; determine the candidate target color whose hue value difference between the hue value and the hue value in the color of each initial legend is greater than the second preset value as a non-similar visual color of the initial legend.

[0091] For example, multiple candidate target colors are asymptotic color 1 and asymptotic color 2, the difference between the hue value of asymptotic color 1 and the hue value in the color of each initial legend is greater than a second preset value, and the difference between the hue value of asymptotic color 2 and the hue value in the color of each initial legend is less than or equal to the second preset value, and asymptotic color 1 is determined as a non-similar visual color of the initial legend. Asymptotic color 2 is determined as a similar visual color of the initial legend, and asymptotic color 2 is deleted. It should be noted that similar visual colors indicate that the difference in hue values ​​of the colors between the legends is less than the preset difference, thereby giving the user the feeling that the colors of the legends are similar in perspective. Similar visual colors indicate that the difference in hue values ​​of the colors between the legends is greater than or equal to the preset difference, thereby giving the user the feeling that the colors of the legends are not similar in perspective.

[0092] Through the above scheme, it is possible to distinguish whether the candidate target color is a similar visual color or a non-similar visual color to the initial legend, and delete the candidate target colors with similar visual colors to reduce the occupied memory space and avoid resource waste.

[0093] In summary, the color matching processing method provided by the embodiment of the present application determines the multiple initial legends pre-configured in the target product and the color of each initial legend; when a new target legend is detected in the target product, the colors of two initial legends are selected from the multiple initial legends in the target product to obtain color one and color two; the target color is determined based on color one and color two, wherein the target color is the middle color of the colors of the two initial legends; the target legend is rendered in the product using the target color, thereby solving the problem of poor color matching effect of the legend in the product. By determining the color of the newly added legend based on the initial legends pre-configured in the target product and the colors of the initial legends, the color is the middle color of the color of the initial legend, thereby avoiding the situation where the color of the newly added legend is repeated or similar to the color of the initial legend, causing color confusion, and automatically rendering the newly added legend with the target color (middle color) obtained by the above scheme, thereby improving the efficiency and accuracy of legend color generation. When the user searches for the legend in the product, he can quickly search and distinguish based on color, thereby achieving the effect of improving the efficiency of searching for content by color in the product.

[0094] Figure 5 is a schematic diagram of an optional color matching method provided in an embodiment of the present application, such as Figure 5As shown, select color 1 and color 2 in the legend of the chart, convert color 1 and color 2 to LCH color space, calculate 6 asymptotic colors including color 1 and color 2 according to the arithmetic progression, use the interpolation of the three values ​​of L (lightness), C (chroma), and H (hue angle) of color 1 and color 2 to correct the 4 asymptotic colors except color 1 and color 2, and then convert these 6 colors back to HSL color space. In addition to the 2 primary colors (color 1 and color 2), the other 4 asymptotic colors are named color A, color B, color C, and color D. In the HSL color space, first convert the hue values ​​of color A, color B, color C, and color D (corresponding to Figure 2 The H value in the chart) is used to calculate the difference between the hue value of color A (the last existing legend in the chart, which is also the adjacent legend to the newly added legend). When the difference is greater than 10, the two are judged to be non-visually similar colors and can be used adjacent to each other. Conversely, if the difference is not greater than 10, the two are visually similar colors and cannot be used adjacent to each other. For example, if the hue values ​​of color A, color B, color C, and color D are all less than 10 with the hue value of color n, then the color with the largest difference in hue value with the hue value of color n is selected. For another example, if the difference between the hue values ​​of color C and color D and the hue value of color n is less than 10, color C and color D are considered to be visually similar colors to color n, and then color C and color D are discarded. For example, if the difference between the hue values ​​of color A and color B and the hue value of color n is greater than 10, color C and color D are considered to be non-visually similar colors to color n. Then, the difference between the hue values ​​of Colors A and B, which are not visually similar, and the hue values ​​of all legend colors in the chart is calculated. If the difference between the hue values ​​of Color A and all legend colors in the chart is greater than 10, Color A is used as the midpoint between Colors 1 and 2, and the newly added legend color is rendered using Color A. If the difference between the hue values ​​of Colors A and B and all legend colors in the chart is greater than 10, for example, the difference between the hue values ​​of Color A and all legend colors in the chart is 18, and the difference between the hue values ​​of Color B and all legend colors in the chart is 12, Color A is used as the midpoint between Colors 1 and 2. If the difference between the hue values ​​of Colors A and B and all legend colors in the chart is no greater than 10, for example, the difference between the hue values ​​of Color A and all legend colors in the chart is 8, and the difference between the hue values ​​of Color B and all legend colors in the chart is 2, Color A is used as the midpoint between Colors 1 and 2. That is, when there are multiple colors that meet the conditions, or when there is no color that meets the conditions, the color whose hue value is the largest different from the hue values ​​of all legend colors in the chart is selected.

[0095] Therefore, through this solution, as long as the color spectrum and the color matching processing method provided by the embodiment of the present application are introduced into the program during the development process, the color of the legend can be automatically and intelligently generated, which can reduce manual intervention and calculation and improve convenience. The technical solution of the present application can ensure that the colors will not be repeated even when there are an infinite number of legends, which is conducive to users to quickly find information through colors and improve the level of visualization. In addition, the color matching processing method provided by the embodiment of the present application can be used in all types of charts and all products involving color generation, and has a wide range of applications. For example, the product involving color generation is a calendar. When making plans in the calendar, specific items are distinguished by color. In the calendar, the study items are configured with green, the work items are configured with red, and so on. When new items are added, the newly added items can be rendered in color based on the color matching scheme of the present application, thereby improving the rendering effect of the new items.

[0096] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0097] The embodiment of the present application further provides a color matching processing device. It should be noted that the color matching processing device of the embodiment of the present application can be used to execute the color matching processing method provided in the embodiment of the present application. The color matching processing device provided in the embodiment of the present application is introduced below.

[0098] Figure 6 Schematic diagram of a color matching device according to an embodiment of the present application. Figure 6 As shown, the device includes: a first determination unit 601, a first detection unit 602, a second determination unit 603, and a first rendering unit 604.

[0099] Specifically, the first determining unit 601 is configured to determine a plurality of initial legends pre-configured in the target product and the color of each initial legend;

[0100] The first detection unit 602 is configured to, upon detecting that a new target legend is added to the target product, select two colors of the initial legends from the multiple initial legends in the target product to obtain color one and color two;

[0101] A second determining unit 603 is configured to determine a target color based on the first color and the second color, wherein the target color is an intermediate color between the two initial legend colors;

[0102] The first rendering unit 604 is configured to render a target legend in a target product using a target color.

[0103] In summary, the color matching processing device provided in the embodiment of the present application determines the multiple initial legends pre-configured in the target product and the color of each initial legend through the first determination unit 601; when the first detection unit 602 detects that a new target legend is added to the target product, it selects the colors of two initial legends from the multiple initial legends in the target product to obtain color one and color two; the second determination unit 603 determines the target color based on color one and color two, wherein the target color is the middle color of the two initial legends; the first rendering unit 604 uses the target color to render the target legend in the target product, thereby solving the problem of poor color matching effect of the legend in the product. By determining the color of the newly added legend based on the initial legend pre-configured in the target product and the color of the initial legend, the color is the intermediate color of the initial legend, thereby avoiding the situation where the color of the newly added legend is repeated or similar to the color of the initial legend, causing color confusion. The target color (intermediate color) obtained by the above scheme is used to automatically render the color of the newly added legend, thereby improving the efficiency and accuracy of legend color generation. When users search for legends in the product, they can quickly search and distinguish based on color, thereby achieving the effect of improving the efficiency of searching for content by color in the product.
