Lighting color application

Color mixing <br> The law of color mixing is the same color spectrum: the color of the object is related to the spectral power distribution of the reflected (transmissive) light, but not one-to-one correspondence, which causes many light with different spectral distributions to cause the same eye Color sense. The phenomenon of metamerism is caused by the low resolution of the human eye, and the metamerism makes coloring easier.

Three primary colors:
Any color light can be obtained by mixing in a certain ratio by not more than three suitable primary colors, and the three primary colors are independent of each other, that is, any one of the primary colors cannot be produced by mixing the other two primary colors.

Three rules of color mixing:
● Complementary color law: color A + color A complementary color = white ● intermediate color law: any two non-complement color mixing = intermediate color ● instead of law: such as: color A = color B; color C = color D;
Then: color A + color C = color B + color D

Additive Color Mixture—Color-light mixing method definition: A method of synthesizing a new color light by using a direct mixing or indirect mixing method using two or more color lights.
Color primary color: CIE regulations; red light (700nm), green light (546nm), blue light 435.8nm

Subtractive Color Mixture—The definition of color mixing method: according to the characteristics that white light is a complex color light and a color material selectively absorbs color light, two or more color materials are used to absorb different color lights in white light, thereby The method of obtaining the desired color. The three primary colors of the pigment, cyan, magenta, and yellow are the complementary colors of the three primary colors of light, red, green, and blue.
