I just looked through several original Advance Design Chevrolet Truck Color Catalogs I have, & most of the Big Bolt wheels are body color. Another thought is if you go with the cab beltline pinstripe color for a red truck which is argent silver, the wheels might look good silver, or gray, to match the pinstrip. I had a black '49 4400 series truck, that I had the wheels, painted the original bumper gray, & they looked good.
