What are the ways to mix colors?

Color mixing is divided into two categories: additive and subtractive. Additive color mixing is also called optical mixing. Its laws are: (1) Complementary color law: Any two colors that are mixed in an appropriate proportion to produce white light are complementary colors. For example, yellow and blue, red and blue-green are complementary colors. When mixing, if the proportion is wrong, it will become an unsaturated color, and the hue will be too much of one color. (2) Intermediate color law: When two non-complementary colors are mixed, a new intermediate color will be produced between them. For example, mixing red and yellow produces orange, and mixing blue and red produces purple. The hue of the intermediate color is biased toward the more dominant color, and the saturation is determined by the position of the two colors in the spectral trajectory. The closer the color, the more saturated it is. (3) Law of substitution: If color A + color B = color C, if there is no color B, and color X + color Y = color B. Then A+(X+Y)=C. Explain that each mixed color itself can also be obtained by mixing other colors. For example, when yellow and blue are mixed, yellow is not necessarily a pure spectral color. It can also be the result of mixing other colors. The final result is still white or gray.
