Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a mind map color matching method, device, equipment and storage medium. Background Art

[0002] In the process of generating a mind map, in order to facilitate user reference, each entity object in the mind map is usually intelligently colored. Specifically, the mind map is colored according to the color scheme in the color theme selected by the user by presetting the color theme.

[0003] However, currently, there are relatively few color themes that users can choose from, and the colors of each color theme are relatively fixed, and their scalability is poor. For example, if a user selects a color theme from multiple color themes with fixed colors, and the color scheme of the color theme stipulates that the background color is yellow and the node color is blue, then in the subsequent color matching process of the mind map, no matter what color adjustment occurs, the color scheme will use the background color and node color, resulting in poor visual effects of the mind map in some cases. Summary of the invention

[0004] The present application provides a mind map color matching method, device, equipment and storage medium, which can improve the scalability of the color matching scheme, thereby enhancing the visual effect of the mind map.

[0005] In order to solve the above technical problems, in a first aspect, an embodiment of the present application provides a mind map color matching method, comprising:

[0006] Performing color comparison on multiple first colors in the target color palette to determine the background color of the mind map, where the first color is the color selected by the user;

[0007] Generate target color matching strategy based on background color;

[0008] Use the target color matching strategy to color the mind map.

[0009] In this embodiment, the background color of the mind map is determined by comparing the colors of multiple first colors in the target color palette composed of the colors selected by the user to meet the user's needs for matching any color without the need to match the color of each node separately, so that the color theme has higher scalability; then according to the background color, a target color matching strategy is generated, and the mind map is matched with the target color matching strategy, so that the color matching between the node color and the background color and between multiple node colors has a more integrated and consistent feel, thereby enhancing the visual effect of the mind map.

[0010] As a preferred embodiment, comparing a plurality of first colors in the target color palette to determine the background color of the mind map includes:

[0011] Calculating first contrast ratios between first colors based on a preset colorimetric model;

[0012] Determine a first label value and a second label value for each first color according to the first contrast ratio corresponding to each first color, wherein the first label value is used to represent the number of first contrast ratios greater than a preset contrast ratio, and the second label value is used to represent the number of first contrast ratios not greater than the preset contrast ratio;

[0013] A background color of the mind map is determined according to a first tag value and a second tag value of a first color.

[0014] This embodiment determines the color with the largest contrast ratio difference by combining contrast ratio with mark value, so as to highlight the color difference between the background color and objects such as nodes and line segments, thereby enhancing the visual effect.

[0015] As an optional embodiment, determining the background color of the mind map according to the first mark value and the second mark value of the first color includes:

[0016] Selecting a second color with the largest first mark value from among the plurality of first colors;

[0017] If the second mark value of the second color is greater than the preset mark value, the background color is determined to be the preset background color.

[0018] This embodiment ensures that the visual effect of the mind map can be optimized by using the preset background color as a fallback solution for the background color when the contrast ratio difference of the target color palette is small.

[0019] As an optional embodiment, after selecting the second color with the largest first mark value from the multiple first colors, the method further includes:

[0020] If the second mark value of the second color is not greater than the preset mark value, detecting the color type of the second color;

[0021] If the color type of the second color is light color, the background color is determined to be the second color.

[0022] As an optional embodiment, after detecting the color type of the second color, the method further includes:

[0023] If the color type of the second color is dark, then the difference between the first mark sum and the second mark sum is calculated, the first mark sum is the sum of the first mark values ​​corresponding to the color type being light, and the second mark sum is the sum of the first mark values ​​corresponding to the color type being dark;

[0024] If the difference is not less than the preset difference, the background color is determined to be the second color;

[0025] If the difference is less than the preset difference, the background color is determined to be the first color in the target color palette whose color type is light color and whose first mark value is the largest.

[0026] This embodiment is based on the principle of light color priority, and uses light colors to be closer to the color of real writing paper. At the same time, light colors as background colors can better highlight the colors of objects such as nodes and line segments, which can meet the user's visual habits and enhance the visual effect.

[0027] As a preferred embodiment, the mind map includes a plurality of node objects and line segment objects for connecting the node objects; according to the background color, a target color matching strategy is generated, including:

[0028] According to the background color, determine the node color of the node object and the segment color of the line segment object;

[0029] According to the node hierarchy relationship of the node object, preset color matching conditions are added to the background color, node color and line segment color to generate a target color matching strategy.

[0030] This embodiment determines the color of node objects and line segment objects at each node level by background color, and adds color matching conditions to generate a complete set of target color matching strategies, so that when subsequent color modifications are performed, overall adjustments can be made based on the target color matching strategy.

[0031] As a preferred embodiment, determining the node color of the node object and the line segment color of the line segment object according to the background color includes:

[0032] Performing a color comparison between a first color in the target color palette and a background color to obtain a second comparison ratio of the first color;

[0033] According to the second comparison ratio and the node hierarchy relationship of the node object, the first color is assigned to nodes to obtain the node color of the node object and the line segment color of the line segment object.

[0034] As a preferred embodiment, after color matching the mind map using the target color matching strategy, the method further includes:

[0035] Obtaining a color modification instruction input by a user, wherein the node color modification instruction carries a target object and a target color, and the target object includes a node object, a line segment object, or a text object;

[0036] In response to the color modification instruction, the target object is modified to the target color according to the target color matching strategy, and the object color of the associated object of the target object is adjusted.

[0037] This embodiment can automatically make adaptive adjustments to other objects of the mind map when modifying the color. For example, after changing the node color, the text color is automatically adjusted without the user having to manually adjust other objects, thereby improving operating efficiency and meeting the need to enhance visual effects.

[0038] In a second aspect, an embodiment of the present application provides a color matching device for a mind map, comprising:

[0039] A comparison module, used for performing color comparison on a plurality of first colors in a target color palette to determine a background color of a mind map, wherein the first color is a color selected by a user, and the mind map includes a plurality of node objects and line segment objects for connecting the node objects;

[0041] A generation module, used to generate a target color matching strategy based on background color, node color and line segment color;

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] As the relevant technical records, such as Figure 2 The mind map shown in the figure is an effective graphic thinking tool for expressing divergent thinking. Each node on the mind map represents a connection with the central theme, and each connection can become another central theme, and then radiate outward to form thousands of nodes, presenting a radial three-dimensional structure. For example, the boxes containing texts such as "MerryChristmas" and "Maintopic" are nodes. By coloring the nodes, users can quickly distinguish the contents of different nodes, improving browsing efficiency and visual effects. However, if Figure 2 The color of the mind map shown in the figure is relatively fixed, and its scalability is poor. If the color scheme of the color scheme specifies that the background color is green and the node color of "MerryChristmas" is red, then in the subsequent color matching process of the mind map, no matter what color adjustment occurs, the color scheme will continue to use the background color and node color, resulting in a single color scheme for the mind map and failure to achieve the best visual effect.

[0055] To this end, an embodiment of the present application provides a color matching method for a mind map, which determines the background color of the mind map by comparing the multiple first colors in the target color palette composed of the colors selected by the user, so as to meet the user's needs for matching any color without the need to match the color of each node separately, so that the color theme has higher scalability; then, based on the background color, a target color matching strategy is generated, and the mind map is matched with the target color matching strategy, so that the color matching between the node color and the background color and between multiple node colors has a more integrated and consistent feel, thereby enhancing the visual effect of the mind map.

[0056] Please refer to Figure 1 , Figure 1The flowchart of a method for color matching of a mind map provided in an embodiment of the present application is shown below. The method for color matching of a mind map in an embodiment of the present application can be applied to computer devices, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, etc. that are equipped with or connected to a display unit. Figure 1 As shown, the mind map color matching method of this embodiment includes steps S101 to S103, which are described in detail as follows:

[0057] Step S101, performing color comparison on a plurality of first colors in a target color palette to determine a background color of a mind map, wherein the first color is a color selected by a user.

[0058] In this step, color contrast is a process of comparing multiple colors based on one or more attributes of color, including but not limited to chroma, brightness, contrast and saturation. For example, the chroma a of color A and the chroma b of color B are calculated respectively, and the chroma difference between color A and color B is compared, that is, chroma difference = chroma a - chroma b. For another example, the chroma a of color A and the brightness L1 are weighted summed to obtain the comprehensive attribute C of color A. Similarly, the chroma b of color B and the brightness L2 are weighted summed to obtain the comprehensive attribute D of color B. The attribute difference between color A and color B is compared, that is, attribute difference = comprehensive attribute C - comprehensive attribute D. It can be understood that there can be many ways to compare colors, which are not limited here.

[0059] Optionally, the mind map includes but is not limited to a plurality of node objects, line segment objects for connecting the node objects, and text objects within the node objects. Figure 2 As shown, the text box where "Merry Christmas" is located is a node object, "Merry Christmas" is a text object, and the line connecting the "Merry Christmas" box and the "Maintopic" box is a line segment object.

[0060] Alternatively, if Figure 2 The target color palette shown includes 6 colors, that is, the target color palette is a color set consisting of a plurality of first colors selected by the user from a plurality of optional colors. Preferably, the number of colors in the target color palette is 6, which is sufficient to form a color matching theme without causing a messy or similar color, and is more in line with the user's visual experience.

[0061] Optionally, the user selects a number of colors from the selectable colors that are the same as the number of colors in the target color palette. For example, if the number of colors in the target color palette is 6, the number of colors selected by the user is also 6. It is understandable that when the number of colors selected by the user is less than 6, new colors can be obtained by performing color transformation on the colors selected by the user to make up to 6 colors, or preset colors can be used to make up to 6 colors. The specific color supplement method is not limited to the above method and will not be repeated here.

[0062] Step S102: generating a target color matching strategy according to the background color.

[0063] In this step, the target color matching strategy is the color matching logic for matching the mind map, which includes but is not limited to the color matching logic for matching the node objects of different node levels, the color matching logic for matching the text objects, the color matching logic for matching the line segment objects, and the color matching logic for the node objects, text objects or line segment objects of the association relationship. For example, the central node is blue, the first-level nodes under the central node are green, the nodes belonging to the same level as the first-level node are red, the text objects in the first-level node are black, and the line segment object connecting the central node and the first-level node is green.

[0064] Optionally, the background color is used as the central color, and the color matching priority of other first colors in the target color palette is determined according to the contrast ratio between the colors, and the target color matching strategy is generated according to the priority. For example, the target color palette includes red, green, blue, white, black and yellow, and white is used as the background color. The priority is determined to be black>red>green>blue>yellow. When generating the target color matching strategy, the color matching strategy for the central node is to use the color with the highest priority, that is, black is used as the node color of the central node, and so on, which will not be repeated.

[0065] Step S103, using the target color matching strategy to color the mind map.

[0066] In this step, the target color matching strategy provides an expert-level serialized color matching combination for the mind map color matching. Figure 5 The mind map shown, with Figure 2 Compared with the mind map, Figure 5 The mind map has richer color features and more distinct and diverse color themes, which avoids the monotonous and boring feeling of the mind map color matching and increases the fun and agility.

[0067] As a preferred embodiment, Figure 1 Based on the embodiment shown, Figure 4 The following is a schematic diagram of the process of determining the background color of the present application. Figure 1The same steps as those in the illustrated embodiment will not be described in detail here. Figure 4 As shown, the above step S101 includes:

[0068] Calculating a first contrast ratio between each of the first colors based on a preset colorimetric model;

[0069] Determine a first label value and a second label value for each of the first colors according to the first contrast ratio corresponding to each of the first colors, wherein the first label value is used to represent the number of the first contrast ratios that are greater than a preset contrast ratio, and the second label value is used to represent the number of the first contrast ratios that are not greater than the preset contrast ratio;

[0070] The background color of the mind map is determined according to the first mark value and the second mark value of the first color.

[0071] In this embodiment, the colorimetric model is a contrast model constructed based on colorimetric theory. Optionally, the colorimetric model is deployed on the computer device. When the computer device executes the colorimetric model, steps including but not limited to format conversion, data linearization, and spectral weighting can be implemented to finally obtain color brightness L, and the color brightness L between multiple colors is compared in pairs to obtain a first contrast ratio.

[0072] Exemplarily, an 8-bit integer (int) is converted into a floating point number (float), that is: R′float=R′8bit / 255.0, G′float=G′8bit / 255.0, B′float=B′8bit / 255.0; the data is linearized to delete the encoded transfer curve, that is, Rlin=sRGBtoLin(R′float), Glin=sRGBtoLin(G′float), Blin=sRGBtoLin(B′float); the brightness is spectrally weighted using the sRGB coefficients, each linearized color channel is multiplied by their coefficients, and then they are added to obtain the brightness Y, that is, Y=Rlin*0.2126+Glin*0.7152+Blin*0.0722.

[0073] It should be noted that each first contrast ratio corresponds to two colors. For example, yellow and blue are contrasted to obtain a contrast ratio X, and the contrast ratio X corresponds to yellow and blue. When the first mark value or the second mark value is counted, if the contrast ratio X is greater than the preset contrast ratio, the first mark value of yellow is accumulated as 1, and the first mark value of blue is also accumulated as 1. Similarly, if the contrast ratio X is not greater than the preset contrast ratio, the second mark value of yellow is accumulated as 1, and the second mark value of blue is accumulated as 1. It can be understood that the larger the first mark value of a color, the greater the difference between the color and other colors, and the larger the second mark value of a color, the greater the difference between the color and other colors.

[0074] As an optional embodiment, Figure 4 As shown, determining the background color of the mind map according to the first tag value and the second tag value of the first color includes:

[0075] Selecting a second color with the largest first mark value from among the plurality of first colors;

[0076] If the second mark value of the second color is greater than the preset mark value, the background color is determined to be the preset background color.

[0077] In this optional embodiment, a second color with the largest difference from other first colors is selected from multiple first colors, but if the second mark value of the second color is greater than the preset mark value, it means that the second color is not much different from other colors in actual situations, so the preset background color is used as a fallback color as the background color. Optionally, the preset mark value can be 1, and the preset background color is white or black.

[0078] As an optional embodiment, Figure 4 As shown, after selecting the second color with the largest first mark value from the plurality of first colors, the method further includes:

[0079] If the second mark value of the second color is not greater than the preset mark value, detecting the color type of the second color;

[0080] If the color type of the second color is a light color, the background color is determined to be the second color.

[0081] In this optional embodiment, the first color in the target color palette is divided into light color, dark color and color. For example, for a given color, the HSL color space is used for processing to obtain its brightness L value. If L is greater than or equal to 80, it is considered to be a light color; if L is less than or equal to 20, it is considered to be a dark color; if L is between 20 and 80, it is considered to be a color.

[0082] As an optional embodiment, Figure 4 As shown, after detecting the color type of the second color, the method further includes:

[0083] If the color type of the second color is dark, then calculate the difference between the first mark sum and the second mark sum, the first mark sum being the sum of the first mark values ​​corresponding to the color type being light, and the second mark sum being the sum of the first mark values ​​corresponding to the color type being dark;

[0084] If the difference is not less than a preset difference, determining that the background color is the second color;

[0085] If the difference is less than the preset difference, the background color is determined to be the first color in the target color palette whose color type is light color and whose first mark value is the largest.

[0086] In this optional embodiment, the light color priority principle is used to further determine the second color. The reason for using light color priority is that light color as the background color will not make the color of the entire mind map too dark, so that some users will not be uncomfortable, and light color is closer to the color of writing paper in reality, which is more in line with visual habits. At the same time, dark color as an embellishment color in the subsequent color matching strategy can highlight the node characteristics. Optionally, the above preset difference is 1.

[0087] As a preferred embodiment, a target color matching strategy is generated according to the background color, including:

[0088] According to the background color, determine the node color of the node object and the segment color of the line segment object;

[0089] According to the node hierarchy relationship of the node object, preset color matching conditions are added to the background color, node color and line segment color to generate a target color matching strategy.

[0090] In this embodiment, optionally, a color contrast is performed between the first color in the target color palette and the background color to obtain a second contrast ratio of the first color; based on the second contrast ratio and the node hierarchy relationship of the node object, the first color is assigned nodes to obtain the node color of the node object and the segment color of the line segment object.

[0091] Exemplarily, the color of each branch of the node object follows the color of its line segment object, such as Figure 5 As shown in the figure, the color of "Main Topic" is the same as the line object connecting it and "Merry Christmas", and its text color is black or white. The color of "Subtopic Fill" is also the color of the line object, and a color matching condition is added to it: change the transparency to 20%.

[0092] As a preferred embodiment, after using the target color matching strategy to match the color of the mind map, the method further includes:

[0093] Acquire a color modification instruction input by a user, wherein the node color modification instruction carries a target object and a target color, and the target object includes the node object, the line segment object or a text object;

[0094] In response to the color modification instruction, the target object is modified to the target color according to the target color matching strategy, and the object color of the object associated with the target object is adjusted.

[0095] In this embodiment, the automatic font color matching enables the user to change the color of the node object and automatically change the text color to a color matching the node object, thus saving the user the trouble of adjusting the font color.
