Description
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
The colors can be positioned by using a color solid, all colors are put into the three-dimensional color solid, but when the colors are regularly arranged on a plane, only two-dimensional information can be used, a typical representative is a custom color palette of a font color selection system of a Microsoft word processing software word system, hue information is horizontally arranged on the plane of the color palette, chroma information is vertically arranged, lightness is limited to a single value, the lightness value can only be adjusted through the right side, the color solid cannot be flattened, and color selection is not visual and convenient.
At present, a patent or a method capable of performing planar arrangement by using a color set with uneven distribution is generally a two-dimensional color space method for dividing colors into hues and other attributes, for example, a method used in an invention patent (a method and a system for arranging color display, application No. 200480039193.6, inventor: mary ross rice) granted in 2007 in China is as follows: "arranging the first plurality of sample cards on the display unit according to the hue and the chroma such that the first plurality of sample cards gradually changes the hue along a first direction and gradually changes the chroma along a second direction. "this results in two-dimensional attributes other than hue being inseparable.
The conventional plane arrangement method is poor in regularity, and multi-dimensional attributes are mainly arranged in the same dimension by subjective arrangement, so that the conventional plane arrangement method is not beneficial to digital application of an automatic arrangement technology. The three-dimensional arrangement method can position the color set, and can comb colors according to positioning information, for example, whether a color gamut with dense colors is a common color or not is necessarily the dense color gamut or even is the dense color gamut, and whether a color gamut with vacant colors has a missing available color or not is determined. It is even possible to analyze the existing color towards which dimension of the three dimensions it changes. But the regularity of the three-dimensional surface is lost when the three-dimensional surface is rotated, and the color analysis and optimization are difficult to realize. This has become a technical problem to be solved.

Further, the number of colors that can accommodate the first dimension attribute per column or row is less than or equal to the maximum number of colors that can be accommodated per column or row.
Further, the method also comprises the following steps:
the specific color in the color stereo and the low chroma color adjacent to the specific color in the color stereo are separately divided into a group of special intervals of a first dimension when the first dimension is divided into intervals; wherein, the specific color is pure gray with only lightness one-dimensional attribute;
when the first dimension partition is in the group of special intervals, the partition is not carried out according to the common main dimension attribute, and the partition is not required according to the first dimension attribute of the normal color interval; selecting a first dimension partition of one of the other two dimensions except the main dimension attribute in the plane space according to requirements; or the first dimension is not partitioned indifferently by attribute.

Further, the acquiring three-dimensional attributes of the color includes:
and positioning the colors through a color stereo to separate the three-dimensional attributes of the colors.
Further, the determining, in a first dimension of the two-dimensional plane, a first color interval based on a first dimension attribute of the three-dimensional attribute by interval division includes:

Further, the number of colors that can accommodate the first dimension attribute per column or row is less than or equal to the maximum number of colors that can be accommodated per column or row.
Further, the method also comprises the following steps:
the specific color in the color stereo and the low chroma color adjacent to the specific color in the color stereo are separately divided into a group of special intervals of a first dimension when the first dimension is divided into intervals; wherein, the specific color is pure gray with only lightness one-dimensional attribute;
when the first dimension partition is in the group of special intervals, the partition is not carried out according to the common main dimension attribute, and the partition is not required according to the first dimension attribute of the normal color interval; selecting a first dimension partition of one of the other two dimensions except the main dimension attribute in the plane space according to requirements; or the first dimension is not partitioned indifferently by attribute.

Further, on a second dimension of the two-dimensional plane, the first color interval is divided based on a second dimension attribute of the three-dimensional attributes to determine a second color interval;
regularly arranging third three-dimensional attributes of the three-dimensional attributes on the second color interval.
Further, in a second dimension of the two-dimensional plane, common principal dimension attributes based on the three-dimensional attributes are regularly arranged on the second color interval.
Taking a three-dimensional space composed of 000-160-level hue, 01-99-level lightness and 01-99-level chroma of a Chinese textile color system as an example, assuming that M irregularly distributed colors are expected to be arranged in a plane of a row and b columns, the colors can be regularly arranged according to the following procedures:
1. introducing a proper color solid, accurately positioning the color, and dividing the color into a color area and a gray area;
for example, three-attribute color stereo of hue, lightness and chroma is adopted by the textile color representation method recommended by GB/T21898; dividing the color with chroma C less than or equal to X (X is generally selected between 00-04) into gray intervals;
2. dividing the color space into different columns according to a first dimension (generally used color phases), determining accommodated color phase intervals according to the maximum color quantity in each column, sequentially arranging adjacent color phase intervals, and determining the total column number;
after each column contains n adjacent color phases, the total number of colors is smaller than and closest to the maximum number of each column; gray, e.g., more than 1 column, high chroma X (e.g., X ═ 4) can be divided into different columns by hue, low chroma X (e.g., X ═ 1) can be arranged by lightness only;
3. each column of colors is divided into i intervals according to the chroma (or lightness) of the second dimension, and the colors are arranged in each interval according to the sequence of the third dimension (lightness or chroma);
for example, the color is divided into 3 to 10 intervals according to the chroma, and the intervals are sequentially arranged according to the lightness; the gray areas are arranged in lightness order only.
The style of the two-dimensional plane graph formed by the method is shown in figure 2, and the hue in the picture can be observed to be reasonably and orderly transited without mutation according to the graph, so that the hue distribution is relatively uniform; each hue interval has a reasonable number of chroma intervals, and the chroma distribution is uniform; each hue interval and each chroma interval have a uniform lightness distribution. From this analysis the following conclusions were drawn:
(1) the color set contained in the color set has relatively uniform distribution in all hue, lightness and chroma intervals;
(2) a somewhat denser distribution in the orange-yellow system (the five uniformly distributed primary colors defined by the cited color solid are reddish yellow, green, blue purple, the number between the reddish yellow of the figure is significantly greater);
(3) if this is a known reasonable distribution data, it can be deduced that the orange-yellow system is the more commonly used and better used color system in this field of application, and if necessary, the distribution density can even be enhanced. If this is not a reasonable number of distributions and the goal is to require absolutely uniform distributions, then the number of beige families needs to be reduced.
In this example, if a conventional two-dimensional histogram is used, it can still be seen that the distribution in one dimension is relatively uniform, but the uniformity in the other two dimensions cannot be intuitively determined.
The method of the invention divides the straight line with the same dimension into a plurality of intervals according to the second dimension parameter, each interval is arranged according to the third dimension parameter, the color information can be arranged very regularly on the straight line and the plane, when a user searches for the color, the user can quickly and accurately position, for example, the user finds out that the target color is not found in the current interval, and can immediately find out the interval with the nearest specified direction according to the dimension information. The problem that color finding is inconvenient due to the fact that the conventional three-dimensional space display unit is complex and the two-dimensional space is irregularly arranged according to an inductive method is solved. The colors arranged on the plane can be conveniently managed by applying regular color space, and the data analysis and optimization of the colors on the plane can be carried out by utilizing the regularity of the color space.
