Not a shade of green unless she was on the set.
I'm thinking something like this could work
Although there was also this 1:5 model that was given to ILM. I like this paint scheme more, it's the closest to the real 1:1, and the paint has some shininess that makes the figure look just like the real thing. Hands down the best I can think of
Unfortunately there's only these two photographs as far as I know.
