Studebaker did have a color called "regal red" in 1963, which was a fire engine red, and I've seen in on Larks. It was never offered on the Avanti though. If one wasn't too much of a purist, one could go with that, and at least it would be a Studebaker color, though not accurate for the Avanti. The Avanti red was a metallic "tomato red" with a hint of orange in it (I think that may come from the metallic flakes in the paint being gold instead of silver colored; I read somewhere that was the case). It's a good looking color, but I had my car repainted, and I wanted to use a non-metallic color, as you can't make an invisible touch up to metallic paint. I almost went with the regal red, as I really think red looks good on an Avanti, but in the end, I wanted to stay more original, and went with one of the only two non-metallic colors Studebaker offered for this car: Avanti white. I only did that after much hesitation, as I really like red on Avantis, and I have never been a huge fan of white as a car color. I have to say, having gone the white, I am very glad I did. Avanti white is not a bright white, it's an eggshell white, almost exactly the same as Ford's Wimbledon white, and I think it looks great on an Avanti.
