The color of the car I currently own was mainly chosen to be easy to maintain (medium blue/grey metallic), but that was before I got into detailing. The color of my next car will mainly be chosen to look good when just detailed

I'm not sure if I'm ready for a black car though...
I don't think I would buy a car just because of the color, but I would strike out a car if it was not available in the "right" color.
