Way back when, 1973 to be exact, I had a 69 six banger standard 3 speed camaro. Colors? Gold bottom with a green yinyl top and a green interior. The top was so dark that unless you were close it looked black. I sold it to a friend of mine when I went overseas. He wouldn't sell it back when I returned. We're still friends and the 69 is a G/SA NHRA racecar.
Green was a popular color in general in the late 60s. While not that many may have been made, green on green was considered a great look in a car.
