My chocolate pudding turned GREEN!!!

Is it safe to eat? I made some SF chocolate pudding a few days ago and decided to make into a protein shake. I put it in the blender, added some NF milk and protein powder, whipped it up and it turned a slimy green color.......did this ever happen to you?  What caused it and is it safe for me to eat?

Ewwwww.....  If it was instantaneous it was probably just some bizarre chemical reaction.  But ewwww.....  I wouldn't eat it.

Are you sure the choc pudding wasn't moldy when you started?  LOL
