Metal coating good latches- gold in color

Does any one know what was the original metal coating on the hood safety latch. Mine is silver almost gav colored but when I removed it the bottom was a gold gav color.

The hood latch "u" type shaped piece should be like the latch.

What is the gold anodized actually called?
Anyone know where to get them done?
The hood is at the body shop today and I fugure what better time to get them re coated.
Thanks,
Joe
