I recently saw a Camaro on the road that was a vivid green (apparently the color is called Synergy Green) with black stripes. It looked awesome. The Camaro doesn't look as good in the metallics, but the Corvette looks good in EVERYTHING.
Of course, the more you can spend for a car, obviously the wilder color options you have, unless you drive a Ferrari, in which case you go with Ferrari Red.
I really need to stop watching shows about supercars that are way out of any price range I'll ever be in.
