Where can I find pictures of color composition and purity comparison?

After more than two kinds of color matching, the color contrast effect caused by different purity is purity contrast. It is another important aspect of color contrast, but it is easily overlooked because of its concealment and immanence. In color design, purity contrast is the key to determine whether the color tone feels gorgeous, elegant, simple, vulgar and subtle.

The intensity of its contrast depends on the distance between colors on the color scale such as purity. The longer the distance, the stronger the contrast, and vice versa.

If the gray to pure bright color is divided into 10 arithmetic progression, 1-3 is usually divided into low purity areas, 8- 10 is divided into high purity areas, and 4-7 is divided into medium purity areas. When choosing hue, when the distance between the primary color and the contrast color is above 5 levels, it is called strong contrast; Grade 3-5 is called medium contrast; 1-2 is called weak contrast. According to this, nine basic types of purity comparison can be divided.

Extended data

The purest color is the primary color. With the decrease of purity, the color will become darker and lighter. The lowest purity means losing hue and becoming achromatic color, that is, black, white and gray.

A bright red and a gray red are juxtaposed together, and their differences in freshness and turbidity can be compared. This comparison of color attributes is called purity comparison. Purity contrast can be reflected in the contrast of different purities in a single tone, and can also be reflected in the contrast of different tones. Compared with pure green, pure red is more vivid.

Pure yellow is more vivid than pure yellow-green. When one of the colors is mixed with gray, the purity difference between them can be clearly seen through vision. Black, white and a saturated tone contrast, including lightness contrast and purity contrast, are very eye-catching color combinations.
