Correct Door Panel Escutcheon Color?

[jcwren]

I'm re-assembling the '70 C10 partial restoration project I bought, and I'm ordering the escutcheons that go between the door panel and window cranks / door handles. The door panels are white metal, and I'm wondering what color escutcheon color would have been from the factory.

As an additional data point, the interior color is Gold Vinyl Trim (622), and the exterior color is Med Bronze (522).

The available choices are black, blue, brown, green, gray, off-white, and red. I'm pretty sure I can eliminate the blue, brown, green, and red ones

What color would the factory have used?

Thanks!
