Can anyone help?

This doesn't seem to be "Mustang specific"; but it may help:

I don't think there were any colors specific to the Coupes as opposed to the FB's :shrug:

EDIT: The very first Mustang I ever spent any appreciable amount of time around was a '67 Coupe (200 I6 and a 3 speed) in Frost Turquoise. Bought it new for himself after he bought a '67 Cougar (same color, but a 289/C4) for his wife.
