Additive Color Mixing

The colors which we see on the screen are created with light using the additive color method. Additive color mixing is based on combination of primary colors – red, green and blue. The combination of two of the primary colors in equal proportions produces a secondary color. It is cyan, magenta or yellow. A wide range of other colors can be created by controlling the relative amounts of red, green, and blue light. The additive color system involves light emitted directly from a source, before an object reflects the light. Combining all three primary colors produces white. RGB system and additive color mixing is used in television and computer monitors. Pixels on a monitor screen start out as black. When the RGB phosphors of a pixel are illuminated simultaneously, that pixel becomes white. Additive color mixing is conceptually simpler than the subtractive color mixing. Subtractive color mixing is the kind of mixing when colored filters are illuminated with white light from behind.
