Color SpaceLast update: Jan 18, 2010
A color space describes the range of colors, or gamut, that a certain device or standard can support. For instance, the range a camera can capture, a monitor can display or a standard can encode.
A color space covers a subset of the entire color spectrum. Some color spaces contain more visible colors than others, or have a larger gamut. Colors that are not supported cannot be reproduced in that color space.
An RGB color space, for instance, lays on the foundations of the colors Red, Green and Blue. The CMY(K) color space, on the other hand, lays on Cyan, Magenta and Yellow.
The RGB color space, for example, is composed of Red, Green and Blue color values. The most saturated red in that color space has an R-value of 255, and G-value and B-value of 0. Any combination of these values defines a different color in the color space.
