1968 Barrcuda grill color

The 68 plastic grills had two different ones and 3 styles
I will just do the left side part numbers as reference
1-part number 2786549 It's the thinnest one, Grey molded colored plastic, the fins are grey. Around the base and the horizontal bars are painted black. On this style grill on the inside (backside) turns like a brownish color after time.
2- part number 2786549 and 2949185 both number on this one also says chrome on it. Slightly darker grey molded plastic and thinker than the one above. Painted the same as above. Stays grey on the back side
3- Same grill as above 2786549 and 2949185 both numbers and the chrome on it. This one was chromed and everything was painted black except the face of the vertical bars that was left chrome.
This what I have come across over the years.
