On my 69 Barracuda the outer shell from the factory looks like light argent silver. The metal egg crate pieces were a slightly darker grayish color but I don't think there was paint on them. Looked like natural metal finish or maybe an anodized finish of some sort, there was no paint flaking off my original egg crates. The Formula S outer shell and egg crates I believe are black. Someone here will know more about the egg crate finish.
