In an embodiment of the present invention, the color feature information includes: saturation, hue, brightness, color collocation relationship, color matching design category, document logic relationship category.

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

"color" in a color scheme refers to color values, regardless of the recording method (4 common color recording systems, RGB, HSL, HSV, CMYK), for example, the RGB system represents a color by saturation, hue, and lightness, and the RGB system represents (255,255,255) black.

After the color value is determined, whether the color value represents a warm color or a cold color, a lively color or a dull color and a brightness range are determined accordingly.

"color matching relationships" in color schemes include, but are not limited to:

the colors are suitable to be used in groups, the colors are mutually visible, the colors are suitable to be displayed in a stacked mode, the colors are in similar relation, and the colors are in contrast relation.

Wherein, "the colors are mutually visible" means that the color composition of the object at the later stage and the color composition of the object at the earlier stage satisfy the distinguishable condition: when the resolvable condition is satisfied, the display content is determined to be visually resolvable, and when the resolvable condition is not satisfied, the display content is determined to be visually indistinguishable.

Wherein the resolvable conditions comprise: and comparing the RGB color composition of the rear-stage object with the RGB color composition of the front-stage object, wherein the comparison result is greater than or equal to a resolution threshold value.

In the embodiment of the present invention, the three components of the RGB color components of the rear-stage object may be subtracted from the three components of the RGB color components of the front-stage object to obtain three difference values, the sum of squares of the three difference values is obtained to obtain a comparison result, when the comparison result is greater than or equal to a preset resolution threshold, the rear-stage object and the front-stage object are considered to satisfy the resolvable condition, that is, the rear-stage object and the front-stage object are visually resolvable, and when the comparison result is less than the preset resolution threshold, the resolvable condition is considered to be not satisfied, that is, the rear-stage object and the front-stage object are visually indistinguishable. For example, a gradation resolution of 256, color 1, RGB (255 ), color 2, RGB (199,237,204), comparison of color 1 and color 2 (255-²+(255-237)²+(255-204)²And comparing the comparison result with a preset threshold value to obtain the visual resolution degree of the color 1 and the color 2, and further comparing the visual resolution degree with a resolution threshold value to determine whether the visual resolution can be realized.

The display content can be generally divided into a plurality of visual levels, for example, when 2 visual levels are available, the visual levels can be called background and foreground, and the colors of the objects in the levels can be called background and foreground; the plurality of visual levels may be referred to as a first level and a second level … … in the display order, where two adjacent or alternate levels are provided, a later level may be referred to as a later level of a preceding level, and a preceding level may be referred to as a preceding level of a succeeding level.

In the embodiment of the present invention, the method further includes:

and setting color characteristic information, and setting a color matching relationship, a color matching design category and a document logic relationship category for the target color.

In an embodiment of the present invention, the color matching relationship includes at least one of the following:

a discernable relationship of a color composition of a back level object to a color composition of a front level object;

a stacked display relationship of a plurality of colors;

similarity relationships between the plurality of colors;

a contrast relationship between the plurality of colors.

In the embodiment of the invention, a preset color pair is set, and the color pair is two colors meeting the distinguishable condition.

In the 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 pair of preset color pairs, white and dark blue (a specific color is determined by RGB color composition) are a pair of preset color pairs, white and red (a specific color is determined by RGB color composition) are a pair of preset color pairs, for example, the color of the rear stage object is black, and the color of the front stage object is yellow.

The embodiment of the invention also sets a series of colors in advance for better visual effect and aesthetic feeling, wherein the series of colors are a plurality of colors meeting the distinguishable condition. One color may correspond to one or more series colors, for example, red, yellow, and green (the specific color is determined by the composition of RGB colors) are a set of series colors, for example, a plurality of filling boxes are included in the same hierarchy, and after one filling box fills red, other filling boxes may select the series colors to fill, and fill yellow and green.

In embodiments of the present invention, if several colors are suitable for use in a group, a series of rules are extracted in conjunction with the structured definition, such as:

1) in the structured definition, a group is considered a group when used;

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

the colors are mutually visible: the colors appearing on two objects in overlying relationship are visible to each other.

Color appropriate display of stacks: the colors appearing on a plurality of objects in overlying relationship are visible to each other.

The colors are similar, and the colors are identified with characteristics according to a set rule. For example: red and orange are similar relationships.

The colors are in a contrast relationship, and the colors are identified with characteristics according to established rules. For example: red and green are in contrast.

The color matching design category is divided into a main color and an auxiliary color.

Combining the logical structure relationship of the document, the method is divided into: background color, color of the cover plate, color of the font, color of the design effect and color of the decoration:

1) background color: from slide background color, substrate color, background picture;

2) character body color: colors appearing on characters and icons;

3) designing effect color: namely other colors, objects such as background, substrate, mask, characters, icons and the like are removed from the whole document, and the colors appearing in the rest objects;

4) coloring: colors that do not appear in other groups, but only appear on decorations that do not overlay any icons or text;

5) masking color: colors that did not appear in the other groups, but only in the mask.

"monochrome, gradient color," is extracted directly from the attributes of the presentation document.
