Interior plastics paint?

Does anyone know the color for the plastic base on the armrests in a '65 Barracuda? What about the dash & radio bezel? Is it the same color? Is it just a basic silver? My interior needs minimal work & those are 2 of the areas. It seems easy enough to do & shouldn't be too expensive. I know that just about anything will make it look better but I wanted to try to keep it original. Thanks.
