Thanks for all the comments guys.
The original carpet would have been dark green and approximate the color of the dash pad.
On various sites, I have seen photos of '65 cars with the dark green carpet that have the Code 68 Ivy Gold/White pony interior. That doesn't necessarily prove anything, but that was the answer I was hoping for because I think the seats and carpet blend well.

Thanks for the photos Charles. The carpet in those cars look like a lighter shade of green to me. Would you hazard to guess what that shade of green might be called? Auto Custom Carpets offers 3 shades - dark green, moss green and olive green. In the Scott Drake catalog, dark green only. Any further help to this newbie would be appreciated.
PS - the color of the console in the two cars look different - one seems more tan colored, the other off white. Was console color an option too?
