Binary partition of the colour space. Assign your colors a number, say 0 through 100. 1 group would yeild the colour at position 0. 3 groups would be 25,50 and 75. 4 would be 0,25,50,100, 5 would be 0,25,50,75,100. Or you could do it with percentage's. 1 group would be 1/1 with would be the colour referenced by 100. 3 groups would be 1/3, the colours would be 33,66 and 100. 5 groups would be 1/5, 20,40,60,80,100. I am sure there is a better way, maybe working directly with the r,g,b values, but i am sure you get the idea of what i am talking about. If each r,g,b value can be between 0 and 255, you could just partition each of those spaces. like 3 groups would yeild the colours (85,85,85),(127,127,127) and (212,212,212). If this makes no sence, just ignore my brain dump....
