Oh, I don't know about that. Consider the reasoning behind "solar sails". The sail is extremely reflective so that light coming after that bounces off and some energy is transfered to the ship. What you'd want would be a silvered back and do whatever you want with the front. In order for any of the colors to make any difference, you need a directional light source -- it MUST be behind you or you won't gain anything. tiny jim madd@bu-it.bu.edu home of "dribble"
