Just go to a local auto body paint store...they have books upon books of different colors. They're usually just chips about 1inch by 1inch...but if you find a color that you like a lot...and want to see a bigger version of the chip, you can get them to spray a test panel that's about 7 inchs by 4 inches. That'll give you a better idea of the color...especially if it's a metallic color.
