Paint Colors and forgiveness...

Hey all! My car is far from paint but occasionally I like to step away from the rust and dream of beautiful paint. My question is this... I am doing the majority of the body work myself. I worked in a body shop when I was in high school. Unfortunately that was about 25 years ago and I haven't done much since. I'm taking my time and doing the best that I can, but I know that there will be some imperfections. I know that white hides and black shows everything. What about silver and grays? I have found a few that I really like. Any suggestions? Color suggestions? She is a '68 Barracuda vert, black interior.
