In this embodiment of the present invention, the color feature information includes the following parts:

The "color" in the color scheme refers to the color value, no matter what recording method is used (there are 4 common color recording systems, RGB, HSL, HSV, CMYK), for example, in the RGB system, saturation, hue, and brightness are used to represent a color, Black is (255, 255, 255) in the RGB system.

After the color value is determined, whether it represents a warm color or a cool color, a lively color or a dull color, and the brightness range is also determined accordingly.

The "color matching relationship" in the color scheme includes but is not limited to:

Several colors are suitable for use in groups, the colors are visible to each other, the colors are suitable for stacked display, the colors are in a similar relationship, and the colors are in a contrasting relationship.

Wherein, "colors are mutually visible" means that the color composition of the next-level object and the color composition of the previous-level object satisfy the distinguishable condition: when the distinguishable condition is met, it is determined that the display content is visually distinguishable; When the discrimination condition is satisfied, it is determined that the display content is visually indistinguishable.

Wherein, the distinguishable condition includes: comparing the composition of the RGB color of the rear-level object with the composition of the RGB color of the preceding-level object, and the comparison result is greater than or equal to the distinguishing threshold.

In the embodiment of the present invention, the three components of the RGB color of the rear-level object can be respectively subtracted from the three components of the RGB color of the front-level object to obtain three difference values, and the three difference values are squared and summed. , obtain the comparison result, when the comparison result is greater than or equal to the preset resolution threshold, it is considered that the distinguishable condition is satisfied, that is, the latter-level object and the former-level object are visually distinguishable, and when the comparison result is less than the preset resolution threshold value , it is considered that the distinguishable condition is not met, that is, the latter-level object and the former-level object are visually indistinguishable. For example, the color scale resolution is 256, color 1, RGB(255,255,255), color 2, RGB(199,237,204), the comparison result of color 1 and color 2 (255-199) ² +(255-237) ² +(255- 204) ^2. Compare the comparison result with a preset threshold to obtain the degree of visual discrimination between Color 1 and Color 2, and then further compare with the discrimination threshold to determine whether they can be visually distinguished.

The display content can generally be divided into multiple visual levels. For example, when there are two visual levels, they can be called background and foreground, and the colors of the objects at the level can be called background color and foreground color; when there are multiple visual levels, they can be displayed according to the display order. , can be referred to as the first level, the second level..., wherein, adjacent or alternate levels, the latter level can be called the latter level of the former level, and the former level can be called the latter level For the previous level of the hierarchy, it is required in this embodiment of the present invention that the background color of the display content must be distinguishable from the foreground color, and the color of the next-level object is distinguishable from the color of the previous-level object.

In this embodiment of the present invention, a color pair may be preset in the setting, and the color pair is two colors that satisfy the distinguishable condition.

In this embodiment of the present invention, color pairs are preset, and one color may correspond to one or more color pairs. For example, white and black are a preset color pair, and white and dark blue (the specific color is determined by the composition of RGB colors) is a pair of preset color pairs, white and red (the specific color is determined by the composition of RGB colors) is a pair of preset color pairs, for example, the color of the rear-level object is black, and the color of the front-level object is yellow.

In the embodiment of the present invention, a series of colors are also set in advance for better visual effect and aesthetic feeling, and the series of colors are a plurality of colors that satisfy the distinguishable condition. A color can correspond to one or more series of colors. For example, red, yellow, and green (the specific color is determined by the composition of RGB colors) is a series of colors. For example, the same level includes multiple filled boxes, one of which is filled with boxes. After filling with red, other fill boxes can be filled with a series of colors, filled with yellow and green.

In this embodiment of the present invention, if several colors are suitable for use in groups, a series of rules are extracted in combination with the structured definition, for example:

1) In the structured definition, grouping is used as a group;

2) The colors that have appeared on the first-level decorations of all slides in the same slide page are regarded as a group;
