The orange listed above was my first thought too. There is a color on the '07-'08 Corvettes and HHR that is nice looking. They both have some pearl/metallics in them though. I did see a 71 Camaro up here with the same base color as the vette but without the pearls mixed in and it really looked good. I would think any decent paint shop could mix it without the pearl in it for you.
