Correct color for these wheels

[Faust]

I just picked up a set of 10 spoke GN/T-type wheels which someone had painted white. In getting the paint off, a couple have what look like original "argent" centers. Most I have seen have no paint on the front and a portion of the rear painted black. Can anyone tell me what the original colors/finish was.

The center caps have the Buick 3 shield emblem, would the GN have something else?

Background on 84-85 GN was black
Plan metal or clear paint on 86-87 T Types all had tri sheild centers
86-87 Gn's had different rims in chrome.
