So I'm guessing there are so many Flesh, Red, Purple and Dark Blue because they were the first colors to be released so had plenty on hand and that they just made up three particular Trees in the soon to be released MUSCLE colors prior to production. I wonder why these three and only these three?
I'm not sure that the info helps out with any MUSCLE theories but I thought I'd throw it out there anyway...
