I believe the car is a 1956 Chevy Bell air. In that year they had two turquoise colors 698 Twilight and 749 Tropical. Based on your photos it looks like the lighter of the two which makes it 749 Tropical Turquoise. Scalefinishes.com matches the original color code with their paint. I have used their Dodge Dark Green Metallic, Aston Martin DBS Quantum Silver and they are spot on, and lay down great. Their prices are good, but you will need an airbrush and I highly recommend a respirator when spraying. Otherwise their paint is superb and when i need a specific color i am continuing to use them
