This Demonstration shows a three-dimensional representation of the visible colors in

xyY

space. The colors are mapped to various RGB working spaces. The

x

and

y

coordinates represent chromaticity (the difference between red, green, and blue), while the

Y

(vertical) coordinate represents brightness. Thus, the set of all possible points in

xyY

space represents all possible hues and brightnesses.
