1, the three law of people mixed colored light eyes not only produces a color for monochromatic light, and the mixed light can also produce the same color. Color mixing phenomenon summed up as three laws: the law of light, middle color Tianjin, instead of law.
The complementary law -- every color has another with its mixture of produce white light, the two colors are called complementary colors. Such as blue and yellow light, green and purple, red and blue mixed can produce white light. In
The two law is that the mixing of the two kinds of non complementary light does not produce white light. For example, red and green, according to the proportion of mixed, and can be between the two orange, yellow, yellow
