Duetz/Allis wheel color

[Htg/Air]

I am cleaning up a 612H Duetz/Allis lawn tractor. Wanting to repaint wheels. What color of spray paint should I purchase?
Thanks!

Thanks for your input! I guess I should have been a bit more specific with my question. What particular color of spray paint would match the original wheel color?
Thanks again
