Additive color

An additive color system involves light emitted directly from a source or illuminant of some sort. The additive reproduction process usually uses red, green and blue light to produce the other colors. Combining one of these additive primary colors with another in equal amounts produces the additive secondary colors cyan, magenta, and yellow. Combining all three primary colors in equal intensities produces white. Varying the luminosity of each light eventually reveals the full gamut of those 3 lights.
Computer monitors and televisions are the most common application of additive color.
James Clerk Maxwell is credited as being the father of additive color: He had the photographer Thomas Sutton photograph a tartan ribbon three times, each time with a different colour filter over the lens. The three images were developed and then projected onto a screen with three different projectors, each equipped with the same colour filter used to take its image. When brought into register, the three images formed a full colour image, thus demonstrating the principles of additive color.
