Repainting my 68 Barracuda fastback

Welcome to Fabo!

The green interior is very limiting on your choices. I am not a fan of the two wild greens you mentioned, but I am old fart.
I loved that yellow back in the day, as it was very complimentory to the lines of the Barracuda.
(I was talked into the Viper Red on my car, wish I hadn't, and painted it silver) My favorite colors on these cars is a Silver or Maroonish wine color. But in your case, with the green interior, maybe a buckskin color would look good?
