Correct oil cap color ('67)

I see many '67's with a silver oil cap on a gold filler console. Correct?
Also, since oil/gas cap is the same, is gas cap silver too?
TIA

silver cap on gold pipe is right for the oil tank, strange as it seems.

OK, but as Brian asked: Should the gas cap then be silver (clear zinc) too (like the oil cap) on a 67S?

On the pictures I have collected, this is what I see:
