It's not about what you're going to get on your car as your primary color.

Some people like colors that just don't look good on everything.

Green is a great example.
Since I already told you mine is better, it's time to explain why. "Oh, dear—why, The_Blur, is your color superior to mine?" That's a great question. I'm glad you asked. Green has significance and value in our society.
As all of you know, green is the American color of success, evidenced in money. Our money, unlike most nations' money, has only one major color, and that color is green. For me, success is important for me to buy a Camaro since I have $0 in the bank right now for it, I will need to make bank after college to afford my Camaro, which I will probably dress with green accenting. Green would cost far too much and look too weird as a paint color for the whole car, so I will add traditional muscle car stripes in green to signify the future success of my Camaro on the track and to symbolize the successful saving and work I would have performed to get my new whip.
I reserve the right to add arguments to assert that my color is better than your color—so there.
