hey bud. I know that ESB had 3 braids: black, a grey "variety", and flaxen blonde. I say "variety" b/c I think there is some color variation in the braid itself. I'm not an ESB expert though.
I think the RotJ/SE braids had some different colors and there are attachment differences (looped under arm vs. hanging from shoulder).
I did an interpretation of the MoM exhibit braids. I have a blonde, brown, black, and a blonde/black. There are also "tails" or shorter braids of grey, brown and black coming off of the blonde/black braid.
I would suggest searching for some of Julie's posts, as I know this has been covered before.
