I'm very glad to see you doing this. I've tried the other available welts in silver and black and not very happy with the fit of either one. The black is not even shaped right.
Your Buccaneer red may work for other reds too, like 79 Mayan red. I might have to paint one of my TA's red just to use it
.
Gotta think Black would be a huge seller. As was mentioned, Solar Gold. 79 Nocturne blue is a good color, and would pass for other dark blue metallics. And silver could cover many years.
P.S., I'll spread the word about your product.
