Mattlov, I would recommend against a color change unless you are willing to do it correctly. Just squirting paint on the outside is not enough, you need to paint all the areas like door jams, under hood and trunk et al. Repaint the can the factory color and add highlight (racing stripes or something). This will end up looking a lot better and keep the resale up unless you try to pass it on to someone who doesn't know better.
I can't tell you how many cars I've inspected and found a really nice paint job and opened the door, trunk, or hood (or all three) and found the dingy dirty original paint in a non-complementary color (think British racing green over purple).
