I plan on doing powdercoating on them. I have a guy that used to do all my coating when I used to make and sell custom motorcycle parts. He usually cuts me great deals. I will see how close he can come to Vermillion Red.
Better to go darker than lighter with the Red. Too light and they will look pink-ish.
If you're having trouble deciding on a color, get some spray paint, do the wheels on one side in one color, the other side in the other color and live with it for a while and see which you like. Once you're decided on the color, take 'em to your powder coater.
For what it's worth, Old Henry somewhat "pimped" his personal '29 Special Coupe (which was all-black) with a red pinstripe (and other little features), so there's my vote for the red stripe, and ( therefore ), "wheels match the stripe", ergo: red wheels.
My '28 Special Coupe came to me the way you see it in my avatar. original colors were Andalusite Blue (VERY dark) with grey stripe, and black wheels (of course). I think the black wheels make for too much dark on the bottom of the car, so when I go back to Andalusite blue, I will match my wheels to the stripe, and perhaps do a spare set in black.
Since you're running 16" wheels, and radial tires, you're already veering quite a ways from "stock", so I think you are entitled to some liberties on wheel color...
( by the way - red wheels go faster !
