Color Spaces
The ColorTools package allows you to work with different color spaces, such as the default RGB (Red Green Blue) space, the CMY (Cyan Magenta Yellow) space or the HSV (Hue Saturation Value) space. A full list is given in the ColorTools/ColorSpaces help page.

⟨RGB : 0.4 0.3 0.8⟩
ColorHSV, 0.5, 0.3,0.8;
⟨HSV : 0.5 0.3 0.8⟩
ColorXYZ, 0.5, 0.6, 0.4;
⟨XYZ : 0.5 0.6 0.4⟩
You can also view colors on the HSV color wheel or a grid of RGB colors with one color channel fixed at a specified value.
