Paint Questions

Anyone know how I can find out what the paint colors available for a 69 barracuda were?

My car was a dark green, almost army jeep green. Anyone know what color code/name this was?

Anyone know were I could see a color sample of the paint colors available for the 69?

I had my 69 repainted, and they are claiming it is the original color, but it is a light lime green instead of the dark green. I know it is not right, and need to research how to prove it.
Thanks for your help.
