Color model

In color science, a color model is an abstract mathematical model describing the way colors can be represented as tuples of numbers, typically as three or four values or color components. It differs from a color space in that a color model is not absolute, that is, there is no way to map a color within a color model to a point in a color space.

This article describes ways in which human color vision can be modeled, and discusses some of the models in common use.
