If you are familiar with the HSA color scheme, the algorithm will be simple.

The color wheel depicts hue and saturation. Hue changes with angle, and saturation changes with radius. For more information, you can take a look at http://www.stackoverflow.com/questions/4235072/math-behind-the-colour-wheel
