With a lot of help from Dan it looks like blue colors supplied by AC or SA are like most things Cobra, not an exact rule. Lots of variables in color, time, solvents, government involvement, painters, guns etc, etc... all make duplicating an original paint from the day near impossible if someone was attempting to do so today. Can Nitrocellulose Lacquer even be bought in the USA now? Even if it can be, the color would be near impossible to match to original and the paint isn't durable at all. As far as Bright Blue goes, it was an original color supplied by AC Cars.
I was thinking Pacific Blue is a color offered on late CSX cars but I could be wrong about that.
