Maclean, I think I can answer this (hope he isn't stepping on Steve's toes by saying this)... The image that has the red and blue polygons with the white trimming, the way it was explained to me is that you are able to paint/color your polygons to the color that you want the hair to come out being. The blue polys will produces blue stands, the red red strands and the white outline white strands. These polys can be multicolored to produce realistic hair coloring. Hope that helps. Jack
