A buddy of mine who knows quite a bit about E said that colors don't mean jack. Typically around here blue means meth based. He said it doesn't matter if its red, orange, blue or yellow or whatever. The only way to know if it is good is to get it tested or take it he said.
Yeah he was right, the colours are just added in for the same reason logos are stamped on them, novelty. Or sometimes but not usually the clours are just the colour of the filler they used.
