Hi, thanks for the response. My problem isn't that I want to change the object color, I want to have the values of the colors of the faces so that I can use them elsewhere. I am taking each face from a polyhedron and displaying it as a flat polygon, but I want the polygon to have the same color as it has on the polyhedron (the outside face, specifically). Any ideas on how to do such a thing? Thanks, AJ David Park wrote: > AJ, > > Use the graphics directives FaceForm, EdgeForm and SurfaceColor.
