My first car was a 67 Mustang that my Dad bought new in 67. He ordered it special with Poppy Red paint. When I got it in 76 it needed paint, and I added two Shelby-ish black stripes down the hood, roof, and trunk. That color combination looked awesome, and at some point I'm going to paint my 68 fastback the same way. My vote is for Poppy Red with some black accents of some sort...
