Well, I can pretty much say that they are usually considered the same color. BTW that's
my '66 convertible on Zim's site. It's definitely a metallic paint, and in some light looks
quite green in color. In other more direct light, it looks more gold.
My door code is Z also. The "original" paint that I have on some areas of my car is a lot less
green and more gold.
So go figure!
Hope that helps.
