How to draw the color purity of color composition?

Color purity is simply understood as color purity, so you only need to add the same amount of other colors to each color, such as choosing a simple big red with a little white for the first time, choosing 1 times the secondary white for the second time, and so on.

Color purity transition is a gradual form of arranging and combining colors from fresh to gray or from gray to fresh according to arithmetic progression's order. Complementary shift is a pure combination shift form in which a pair of hues at both ends of the color ring pass through the center of 180 degrees.

Extended data

Color transition is a special form of works, and its composition and image organization also have corresponding characteristics and basic laws.

1. Parallel shift is to orderly arrange and process colors according to parallel vertical lines, horizontal lines, oblique lines, curves or irregular stripes with equal or unequal intervals.

2. Radiotransmission

(1) fixed-point radiation is also called solar radiation and centrifugal radiation. One or more radiation points should be determined in the picture, and then the combined colors should be arranged at equal or unequal angles around the incident point.

(2) Concentric radiation is also called radio wave radiation. The picture has one or more radiation centers, from which the colors are made into concentric circles, concentric squares, concentric triangles, concentric multilayer, concentric irregular shapes, etc. , and spread outward.

(3) Comprehensive radiation organizes fixed-point radiation and concentric radiation in a picture.

3. Comprehensive transition: Parallel transition and radial transition appear and are arranged in a picture at the same time, which makes the modeling of the work form the contrast of curve, straight, wide, narrow, thick and thin, the composition is complex and changeable, and the effect is more interesting. However, in order to prevent the disadvantages of scattered, chaotic, colorful and miscellaneous, the picture should generally have only one center or one subject, or one subject at a time, avoiding multi-center and multi-subject.

4. Dislocation, overlapping and deformation

There are two types of (1) dislocations: global dislocation and local dislocation. The whole dislocation is to compare the cold and warm tones, brightness and fresh gray purity, and to arrange the colors of the background and the picture in the whole and in the opposite direction. For example, the background color changes from cold to warm, the picture color changes from warm to cold, the background color changes from bright to dark, the picture color changes from dark to bright, the background color changes from fresh to gray, and the picture color changes from gray to fresh.

Local dislocation is a method used to deal with the color arrangement of regular blocks. For example, the first row is colored with 1, 2, 3, 4, the second row is colored with 2, 3, 4, 5, and the third row is colored with 3, 4, 5, 6, and each row is staggered by one or more levels. Sometimes, for the needs of some light perception and stereo processing, it can be shifted to the left and right sides at the same time. For example, the color of 1, 2,3,4 is used in the first row, and the colors of 2,3,4,5 are used in the second row at the left and right for symmetrical dislocation.

(2) Penetration means that when two shapes overlap, they can be regarded as both shapes and outlines. Color superposition can produce transparency and lighting effects, which is very interesting and modern. When the bottom shape and the surface shape overlap, if the color difference series is small, the closeness of the two is small. When the color difference increases, the sense of space between them also increases and there is a sense of distance.

(3) There is a lot of room for the variability and creative development of deformed colors. After mastering the basic composition form and the rule of phoenix color, we will make various changes and give full play to our personal imagination, which will produce endless masterpieces.

There are many forms of change. For example, the radiation emitted by a fixed point is generally treated as a straight line, which can be treated as an arc deformation, a windmill that rotates in one direction, or a two-way intersection, which makes the effect more complicated and rich.
