Neptune Green was not a standard color on a '55 T-bird. As best I can tell it was only offered on the Fairlane that year, so if this is factory (which it sure looks like up close; it's just tatty enough around the edges to be unrestored) it was a special order item.
Of course, in '55, you could even special order your T-bird in primer so you could paint it yourself.
