Just wanted to update everyone. I stripped the paint off the insides of my housings and took a picture:

You can clearly see that they are gold in color. My plater said that the finish is Alodine which is a product I actually have some knowledge of. It's a hexavalent chrome (the chemical that the movie Erin Brokavich was about) based corrosion inhibitor commonly used in the aircraft industry to protect aluminum and that has been banned in Europe. Anyway, I don't feel like taking the effort to find someone locally to do it so I'm going to paint them. Because everyone is used to seeing a grey cast finish, I'm going to go with a similar color.
