Orange? Post on HAMB (https://www.jalopyjournal.com/forum...p-thread-to-end-all-photoshop-threads.300531/) and see if you can get one of the photoshop guys to show the different color wheels. Should be easy for them compared to some of what they do. Your fenders don't look very brown, maybe the light. Be sure to get a high resolution copy to the guy(s) doing photoshop.
Tan like the body, or red or orange if you want something more colorful. Here's a link to Marco's site where you can play around with different colors on a roadster.
For many years I painted all of my model A wheels a light yellow , if I painted them at all . I finally got tired of yellow wheels and now mostly paint my model A wheels red . I like the orange wheels on the pictured huckster and that would be my choice .
The more I think about it and after reading the comments, I think I'll go with the color of the body with a brown pin stripe with blackwalls. Not colorful but as John Boy Walton said, "a respectful color"
