Why did my hair turn green?

I had streaks of purple put in my hair back in February and now that's the purple is fading I wanted to try and just get the purple out to be left with the bleached streaks so I tried a lift (I think that's what the girl at Sally's called it) but after leaving it on for an hour my hair turned that brassy red and green. Why did it turn green?

It might be because the purple is red and blue mixed together and when you tried to lift it the primary pigments in the dye did not fully lift. I'm no expert on color but I think thats what happened and you might need to see a professional if you want blonde
