Color Theory

Colors can also be modeled using "spaces". Two simple ways are through the RGB color space (which comprises the levels of red, green, and blue light that our eyes perceive), and through the HSV color space which rather uses the dimensions of Hue, Saturation and Value. A more sophisticated kind of color space is represented by the CIELAB color space, in which the distance between points in the space corresponds directly to the perceived difference between the colors to a human viewer.

Topology

The color spaces are generally three-dimensional (given the three different kinds of cone cell receptors in the human eye, with sensitivies to different ranges of frequences), and are approximately cylindrical, spherical or cubic depending on the nature of the model:
