Fizzed, smoked and went yellow?

[mashead testing]

I tested some green mitsis today with marquis and they fizzed, smoked then went yellow I tested from different parts in the pill and tested 5 different pills from the batch all did the same.
I have looked through the list of reactions and the closest reaction was for foxy however I find that unlikely.
Has anyone else got any ideas, there are a few pillreports for very similar sounding pills all of which suggest very speedy.

Yeah I saw bzp, I must admit my curiosity got the better of me and I tried it, it was speed like substance but it had some strange properties to it which I find very hard to describe.
