You don’t have to choose your favorite car color in general - you can pick a color that you think looks great on a specific car.
My first choice is “Liquid Copper” for the Infiniti FX.
I haven’t seen many (or any) other cars that can pull off orange with such elegance.
Second choice is “White Diamond Tricoat” for any Cadillac (with obvious bias)
So what’s your pick?
