What are the Sources of Light?

The source of light, a primary color of light, it is the RGB (red, green and blue). When talking about photography in class, we mention the primary colors. In addition, we watch TV in the fluorescent powder is also this kind of combination, the color CRT, but don't look at the computer monitor in front of you, the pixel is too small, the naked eye could not tell. The combination of these three colors RGB, almost form almost all of the color.

The light gets brighter, and a combination of two or more colors can produce a brighter medium: yellow, cyan, and magenta.

Complementary color refers to the complete absence of another color, red and green mixed into yellow, because there is no blue, so yellow is the complement of blue

The second tricolor is the printing tricolor

We see the color of the printing, actually the reflected light of paper. When we paint the color, we also want to use this combination. Pigments absorb light, is not the light of superposition, so the three primary colors of pigments are able to absorb the RGB color, cyan, yellow (CMY), they are complementary color of RGB color.

When you mix yellow pigments with cyan pigments, because yellow pigments absorb blue light and cyan pigments absorb red light, only green light is reflected. This is why yellow pigments plus cyan pigments can form green.
