Description

A way to arrange colors on a plane

technical field

The invention relates to the technical field of color data processing, in particular to a method for arranging colors on a plane.

Background technique

Colors can be positioned by color stereo, and all colors are placed in a three-dimensional color stereo, but only two-dimensional information can often be used for regular plane arrangement. The typical representative is the customization of the font color selection system of Microsoft word processing software word system. The color palette, on the plane of the color plate, is the hue information horizontally, the chroma information vertically, and the lightness is limited to a single value. You can only adjust the lightness value through the right side, and the color cannot be flattened. The color selection is not very intuitive. convenient.

At present, the patents or methods that can use unevenly distributed color sets for plane arrangement are generally two-dimensional color space methods that divide colors into hue and other attributes. Method and System, Application No./Patent No.: 200480039193.6, Inventor: Mary Rose Rice), the method used is: "Arrange the first plurality of sample cards on the display unit according to hue and chromaticity, so that all The first set of multiple sample cards gradually changes the hue along the first direction, and gradually changes the chromaticity along the second direction." This results in that the two-dimensional properties other than the hue cannot be separated.

The regularity of the existing plane arrangement method is not good, and the arrangement of multi-dimensional attributes in the same dimension mainly relies on subjective arrangement, which is not conducive to the digital application of automatic arrangement technology. The three-dimensional arrangement method can locate the color set, and the colors can be sorted out according to the positioning information, such as confirming whether the color gamut with dense color is a common color, whether it is necessary to be so dense or even denser, and confirming whether the color gamut of the color vacancy is missing. Available colors. It is even possible to analyze in which dimension of the three-dimensional the existing color should change. However, the regularity is lost when 3D is transferred to the plane, and color analysis and optimization are difficult to achieve. This has become an urgent technical problem to be solved.

SUMMARY OF THE INVENTION

In view of this, the present invention proposes a new method for regularly arranging the three-dimensional attributes of colors on a two-dimensional plane, which can regularly arrange color sets with uneven distribution on the plane, and can automatically change the arrangement at any time according to color changes. , and can also easily perform color analysis and optimization on the plane.

The present invention will be further described in detail below in conjunction with the accompanying drawings and examples.

The present invention regularly arranges three-dimensional colors on a plane, taking the three-dimensional space composed of hue, lightness and chroma as an example:

On the first dimension of the plane, it is arranged according to the one-dimensional (generally using the hue interval) of the three-dimensional rule, and the second dimension of the plane uses the remaining two dimensions of the three-dimensional, firstly divided into different intervals ( For example, different brightness intervals), and rearrange the third-dimensional information (such as chroma) in each brightness interval. In this way, you can quickly find the position of the color of any hue, lightness, and chroma on the plane.

FIG. 1 is a schematic flowchart of a method for arranging colors on a plane. A method for arranging colors on a plane of the present invention, comprising:

Get the three-dimensional properties of the color;

Further, it also includes:

Taking the three-dimensional space composed of 000-160 hue, 01-99 lightness, and 01-99 chroma of the Chinese textile color system as an example, suppose there are M colors with irregular distribution, which are expected to be arranged in the plane of row a and column b. Inside, the colors can be arranged regularly according to the following process:

1. Introduce a suitable color stereo, accurately locate the color, and divide it into a color area and a gray area;

For example, use the three-attribute color stereo of hue, lightness, and chroma as recommended by GB/T21898 for textile color representation; divide the colors with chroma C≤X (X is generally selected between 00-04) into gray intervals;

2. Divide into different columns according to the first dimension (usually use hue), each column determines the hue range accommodated according to the maximum number of colors, and arranges adjacent hue ranges in sequence to determine the total number of columns;

Among them, after each column accommodates n adjacent hues, the total number of colors is less than and closest to the maximum number of each column; if gray exceeds 1 column, the chroma X is high (for example, X=4) can be divided into different columns according to hue, chroma Those with low X (for example, X=1) can be ranked by lightness only;

3. Each column of colors is divided into i intervals according to the second dimension chroma (or lightness), and each interval arranges the colors according to the order of the third dimension (lightness or chroma);

For example, according to the chroma, it is firstly divided into 3-10 intervals, and each interval is arranged in the order of brightness; the gray area is only arranged in the order of brightness.

The resulting two-dimensional floor plan style is shown in Figure 2. According to this figure, it can be observed that the hues in the picture transition in a reasonable and orderly manner, without sudden changes, and the hue distribution is relatively uniform; each hue interval has a reasonable amount of chroma The chroma distribution is also uniform; each hue interval and each chroma interval have a uniform lightness distribution. From this analysis the following conclusions are drawn:

(1) The color set contained in the color set has a relatively uniform distribution in all hue, lightness and chroma intervals;

(2) In the orange-yellow series, there is a slightly denser distribution (the five uniformly distributed main colors of the referenced color stereo definition are red, yellow, green, blue and purple, and the number between red and yellow in this figure is significantly larger);

(3) If this is a known reasonable distribution data, it can be deduced that the orange-yellow color system is a more commonly used and better color system in this application field, and its distribution density can even be enhanced if necessary. And if this is not a reasonably distributed quantity, and the goal is to have an absolutely uniform distribution, the number of beige shades needs to be reduced.

In this example, if a conventional two-dimensional plane distribution diagram is used, it can still be seen that the distribution of one dimension is relatively uniform, but the uniformity of the other two dimensions cannot be intuitively judged.

The method of the present invention divides the straight line of the same dimension into several intervals according to the second dimension parameter, and then arranges each interval according to the third dimension parameter, so that the color information can be arranged very regularly on the straight line and the plane, and the user is looking for When it comes to color, it can quickly and accurately locate. For example, it is found that the target color is not found in the current interval, and the nearest interval in the specified direction can be found immediately according to the dimension information. It avoids the problem of inconvenient color finding caused by the complicated three-dimensional space display unit and the irregular arrangement of two-dimensional space according to the perceptual method. The colors arranged on the plane can be easily managed by the regular color stereo, and the regularity of the color stereo can be used to analyze and optimize the color data on the plane.
