[ first embodiment ]
Referring to fig. 1 to 3, a color template generating method according to a first embodiment of the present invention includes, for example, steps S11 to S19.
As shown in fig. 1, step S11: acquiring an initial color template, wherein the initial color template comprises a comparison relation table of initial theme colors and initial colors of a plurality of elements, and the initial theme colors and the initial colors are characterized by a plurality of color component values of a target color space;
step S13: responding to a user instruction to acquire a target theme color;
step S15: obtaining a plurality of color component values of the target color of each element in the target color space based on the relative relation between the target theme color and the plurality of color component values of the initial theme color in the target color space and the comparison relation table;
step S17: correcting color component values exceeding a preset color range in the target color of each element to determine the target color of the plurality of elements under the condition that at least part of the color component values in the target color of each element are judged to be located outside the preset color range; and
step S19: a new color template is generated based on the target theme color and the target colors of the plurality of elements.
As shown in fig. 3, in step S11, the mentioned table of the comparison of the initial theme colors with the initial colors of the plurality of elements is used, for example, to characterize the comparison of the initial theme colors with the initial colors of the plurality of elements in the initial color template shown in fig. 2. In fig. 2, where the initial theme colors are represented in the drop-down boxes, each box below represents the initial colors of a different element. The plurality of elements include, for example: the main background color, the module ground color, the label selected color, the screen selected color, the frame color, the background color, the font color and the like. In the look-up table, the initial subject color and the initial color of each element are each characterized by a plurality of color components of a target color space, such as the RGBA four-channel color space, then each of the initial subject color and the initial color of the plurality of elements may be represented as, for example, R, G, B, A four color components. Of course, the target color space may also be an RGB three-channel color space, and then each of the initial subject color and the initial colors of the plurality of elements is represented as R, G, B color components, respectively.
In step S13, the mentioned user instruction is, for example: the user selects the required theme colors through a drop-down box shown in fig. 2 and issues corresponding instructions, and the upper computer acquires the instructions to obtain the theme colors selected by the user as target theme colors.
In step S15, based on the relative relation between the target theme color and the plurality of color component values of the initial theme color in the target color space and the comparison relation table, a plurality of color component values of the target color of each element in the target color space are obtained, for example, as follows: obtaining a transformation coefficient corresponding to each color component value according to the relative relation between the color component values of the target theme color in the target color space and the color component values of the initial theme color in the target color space, and transforming the color component values of the initial color of each element in the comparison relation table through the transformation coefficient to obtain the color component values of the target color of each element in the target color space.
Further, the mentioned relative relationships include, for example, a difference operation relationship and a ratio operation relationship, and of course, the relative relationships may also be a multiplication and division operation and a combination operation by a fixed coefficient, which is not limited in the present invention.
In step S17, it is determined whether at least some of the color component values of the target color of each element are within a preset color range, and color component values exceeding the preset color range in the target color of the element are corrected. The preset color range mentioned is, for example, 0-255, and it is determined whether the obtained target colors of the plurality of elements are within the preset color range of 0-255 in R, G, B of the RGBA color space, and the color component values exceeding the preset color range are corrected to determine the target colors of the plurality of elements.
Further, when it is determined that the target color of the font has a color component value exceeding the color range of 0-255 in the R, G, B color component values of the RGBA color space, for example, the color component value is reversely valued, for example, when a certain color component value of the target color of the font exceeds 255, the color component value is subtracted by the color range boundary value 255 to realize the correction of the color component value.
Further, when it is judged that the target color of each of the plurality of elements other than the font color has a color component value exceeding a color range of 0 to 255 in R, G, B of the RGBA color space, for example, the color component value is corrected to a boundary value 255 of a preset color range.
Further, the color template generating method of the present invention further includes: and under the condition that at least partial color component values in the plurality of color component values of the target color of each element are judged to be in a preset color range, if the difference value between the plurality of color component values of the target color of the font and the plurality of color component values of the target color of the background color is not larger than a preset threshold value, reversely taking the color component values of the target color of the font which are not larger than the preset threshold value.
Specifically, for example, when the target color of each element is within a preset color range of 0-255 in R, G, B color component values of the RGBA color space, and the difference between a certain color component value of the target color of the font and the corresponding color component value of the target color of the background color is smaller than a preset threshold value, for example 128, the color component value of the target color of the font is reversely valued. For example, the R color component value of the target color of the font is 200, the R color component value of the target color of the background color is 256, the difference between the R color component value and the R color component value is smaller than the preset value 128, and the R color component value of the target color of the font is far from 256 by a certain value between 0 and 128, so that the difference between the R color component value and the R color component value is larger than 128.
In step S19, a new color template may be generated according to the target theme color selected by the user and the target colors of the plurality of elements obtained. The color template generation method is applied to a browser end, a software end and the like, and a user can select the theme of the full color gamut according to the needs.
In summary, in the color template generating method provided in this embodiment, by obtaining an initial color template, which includes a comparison relation table of initial theme colors and initial colors of a plurality of elements, and characterizing the initial theme colors and the initial colors of the plurality of elements by a plurality of color components in a color space, respectively, obtaining a target theme color and obtaining the target colors of the plurality of elements based on the relative relation between the target theme colors and the plurality of color components of the initial theme colors and the initial colors of the plurality of elements, the color template generation of the full color gamut can be realized; and by judging whether a plurality of color component values of the target color of each element are in a preset range or not, reversely taking values of the color component values of the font color exceeding the preset color range and having a color component value difference with the background color smaller than a preset threshold value and taking boundary values of the color component values of the other elements except the font color, the problem of incomplete information display caused by the conflict of the main tone, the character color and other project colors when the color template is generated can be avoided.
