Well you can't go wrong with Black for the color of the shirt or even a dark blue. The lettering for the Camaro 5 group could be red if it's a black shirt and perhaps yellow if it's a dark blue shirt.....I think either one would be great....For the logo on the back would it be possible to get a 5th Gen Camaro on it instead of the Chevy logo? Just a thought....looking forward to what will be decided.........
