Software/Online to change color of my car?

Honestly you’ll get a better idea of the colors looking at pictures of other cars. Unless you’re a photo editing guru the colors you’re putting on your car won’t be very true to the real paint colors you’re considering. I’m mean sure, you can make it green, but will it really be sublime? Will the lighting be the right?

The problem is the editing software good enough to do it right is hard to use. And the stuff that’s easy to use won’t get it right. Just my .02.
