That'a a cool color. The challenge with a 1st gen Camaro in this industry is having one that's different. I like that color because it says Pro Touring all over it but it wouldn't be just another charcoal grey 1st gen Camaro. A tan interior would really set it off and punch out the green shade.
If you've considered seeing it on paper first through a rendering shoot me a pm, I'd love to give you a bid. Samples at the links below.
Good luck with the build, looks like a great start!!
