Hi Kris and Kristen!
I run the GT/CS Registry, and look at for a private message from me...
What color? Black and dark colors get 20 degrees hotter in the sun. Highland green is the same color as the Bullitt Mustang...
If the sky is the limit for a color, Honda makes this great red color, you might want to check out (watch cars on the road, and see what color(s) grab you). A red CS with Shelby ten ('67-68 type) spokes, and a black vinyl top would look awesome! (with white stripes, too).
I wouldn't be too concerned about the high visibility on the road. If anything, it would be a safety issue as a bright color. Black, at night, may be too dark. if you have the saddle interior, the red would work just fine.
Just avoid putting steer horns on the hood, and silver dollars sewn into the seats...LOL!
Thanks--and welcome.
