解剖色彩（Anatomical color） Color principle About painting, image, nature cannot do without talking about color, all patterns are composed of basic shapes and colors, color constitutes an important part of our image processing, below we will examine the color principle, it will be the basis of our artists. (a) the principle of three primary colors Physics class in high school we have done the prism test, white light through a prism is decomposed into various colors after chromatography gradually, the color was red, orange, yellow, green, green, blue, purple, which is visible spectrum. The eye of the red, green and blue are the most sensitive, the human eye is like a three receiver system, most of the color can be red and green and blue according to different proportion produced. Most of the same monochromatic light can also be decomposed into three RGB color. This is the most basic principle of colorimetry, namely the principle of three primary colors. The three primary colors are independent of each other, any color can have the other two colours. RGB is three colors, the three colors of the color range of synthesis is the most widely. Red green and blue three primary colors according to the different proportion of additive color mixing is called additive color mixing. Red + Green = yellow Green + blue = blue Red + blue = magenta Red + Green + blue = white Yellow, cyan and magenta are composed of two kinds of color and blend, so they are also called the sum of two colors. In addition: Red + blue = white Green + magenta = white Blue and yellow white So, yellow, magenta and cyan respectively are red, blue and green color. Because each persons eye for the same color feeling is different, so, if we use the same strength of the three primary hypotheses are mixed, the intensity of white light was 100%, when peoples subjective feelings, the green light, red light and blue light. In addition to additive color mixing addition subtractive color mixing method. The white light, red
