Is it difficult to paint cars? Where can I study?

Color matching is a friend without teaching materials. Teaching materials are just groping for themselves, being explained by the master, and then accumulating time. Let me introduce my experience in color mixing to you. You can refer to the basic color composition that colorists all know: red, yellow and blue. These three colors are called primary colors, and the colors mixed by these three colors in different proportions are called composite colors. Each color can be determined by three parameters, namely hue, lightness and saturation. Tone is the characteristic of different colors, which determines the chromatographic composition of light source and the feeling of the wavelength reflected by the object surface to human eyes, and can distinguish the characteristics of dividend, yellow, blue, green and purple. Brightness, also known as lightness, is an eigenvalue representing the change of object sensitivity. Saturation, also known as chromaticity, is an eigenvalue representing the depth of color on the surface of an object. Adding white to color matching can dilute the primary color or composite color and get colors with different saturation; Adding different amounts of black can get different "lightness" of colors. There is no such thing as a textbook, but you can find a textbook for drawing, because you must be sensitive to color in order to tune quickly and accurately.
