Why does protein turn green??

[cccp]

you know how when you don't wash your protein shake bottle, and leave it with some leftovers overnight, or for two days, the shit inside turns from white to green! I wonder why does it happen? May be it's just the kind of protein I'm using: Labrada whey? Nah, I doubt it. I mix it with water, but I used to mix it with milk back in the days, and it would still turn green after a while. WHY!!!!!
