I'd like to figure out a new color scheme for a '66 Caprice, possible new wheel treatment, but would like to see a rough sketch before I spend the cash to do it right. Is anyone familiar with any computer software/programs, either available online or through paint companies/body shops where you can input a picture of your car and then tweak the colors, etc?

I've heard of software at tire shops where you can do it with wheels to get an idea of what the final look should be.

Thanks for any input.
