Have you tried a shader (c 2.1): Place the default blue plastic shader, then put a mixer in the color channel, then in the blender put in tiles, 1 horiz and 2 vertical (or reverse them) then in the sources put in your colors. BadaBoom, badabing, you got your two colors. The colors will be pretty equal in size. Instead of the color, I believe you could put in your image map, if you want. hth
