The human eye can see up to 10,000,000 colors. All of these colors derive from two main types of light, additive or subtractive.

Additive Color, commonly known as RGB, is made up of red, blue and green. The combination of these three hues make white. Additive color is used in digital photography, computer moniters and televesion displays.

The concept behind RGB that when you add colored light to your black monitor or TV screens, it gets lighter. The more color you add the lighter the screen appears as you are adding colored light to black.

Subtractive Color, usually known as CMYK is primarily made up of cyan, magenta and yellow. The combination of these three hues make black. In the printing process black is added and denoted by the letter K.

Subtractive color is most commonly used in printing and in the mixing of paints and dyes.

The concept behind the subtractive color model is that you subtract light from a white surface by applying ink, paint or dye. The more color you put on a white surface, the blacker it gets,
thus you are subtracting light from white.
