I take it you mean the color my Scamp was when I bought it. That was an easy choice for me to make (the color I went with, as in my sig, is ford chrome yellow).
I agree with Purple Haze. And, afaic, a 'nicer' color (as long as a prospective buyer agrees that it's a nicer color) won't hurt resale value- as long as the car hasn't had major irreversible changes made to hurt the ability to turn it back to stock.
