The Cobra shown in the 1962 New York auto show was pearl yellow. That is the first time the public got to see the car. It had a 260V8 in it and was never raced. It ended up being a test mule and was eventually parted out. It would be the only time a Cobra was ever shown in that color. It was hand built by Shelby in his shop.
The color of the car depended on if it was the race version, or the production version. The small block race cars were red. The big block race cars were blue.
In the production version of the small block car, you had a choice of black or white.
The big block car allowed for rangoon red, gaurdsman blue, ivy green, white, and silver.
There were 13 original AC colors.
gaurdsman blue, dark blue, mist silver, ruby red, canary yellow, light green, rosso chiaro, pure white, mushroom, vineyard green, live oak, sand, and princess blue.
