The best colors for me are red on white, with mostly red. He uses a lot of pink and neon orange lately. The guys in his clubs razz him a bit about some of his schemes, but you have to able to see the plane. If I get a chance I get some more colorful pictures. He has 39 total planes in his basement now.
I also like the black and white checker board covering on the bottom of the wing, helps with orientation. Here's one of his normal looking ones. The cowl is actually a 64 oz. soda bottle cut in half. He doesn;t fly it because he says the light blue is hard to see. I agree.
