There is an orange that supposedly was a Chrysler color called Hemi Orange. Used to be a 73 or 74 Cuda running around here that color, it had a shine and depth to it I haven’t seen since. Don’t know if it was factory paint or not, I was only about 15 years old, but it stuck in my mind as the perfect orange. Have seen a few since then, but none had that depth look to them. No pics, didn’t even own a camera back then.
