I recently sprayed the interior of my 52 GMC with the Chevy Duty interior paint. I would describe it more as a flat grey metal metallic, somewhere between cast iron and stainless steel with just a hint of bronze or brown shading. Actually, mushroom metallic (as I have heard it described) comes pretty close to a verbal description. Anyway, the color of the paint supplied by Chevy Duty did closely match original paint found in my interior. A word of caution though: the Chevy Duty paint is enamal that requires a hardener, which you must order from a seperate supplier (Sherwin Williams brand).
I hope this helps some!
