I went black on my Firebird, had to. I went back and forth for months on it, but the wife and the painter both forced me.
Granted, there are some flaws that would never be seen on another color, and I'm having to learn all the steps in wet sanding/buffing but there is nothing better when it's clean! Heck, just getting to the swirl remover on the first fender last night was a jaw dropping experience!
I went with black over parchment for the contrast.
