I'd suggest you also go with a colour that isn't going to be hard to sell and doesn't decrease your selling market when the time comes.
I'm saying this from experience I've seen people have in the past when they've painted their car pink, and it decreases their sales market to mainly girls.
Just think of things like that when you are thinking of painting your car. Also remember that the current "Fad" is sparkles/flecks/glitter, don't do it just because it's the current trend, do it cause you like it. Also, remember with the future and selling it, are people going to want flecks/sparkles in their paint when time comes that you want to sell it?
Just some pointers if your thinking of changing the whole colour on the car.
