1970 Duster Grill Color

Does anyone know the correct colors for a 70 Duster grill? Is it an argent silver like the 70 Cuda's used? How about the black (semi or flat).

Thanks

Dark argent apron with black center on 340 cars and I believe black everywhere on others.

It was dark argent in 1970 and then black in 1971 but I think the fins were black, only on 340 cars in 1970.
