Manic Panic Green Envy Info

hello everyone! I have dark blonde hair that is color treated and I'd love to achieve a deep deep green head of hair, but I really don't want it to be permanent. I understand that green and blue dyes stain hair more than others, but I'm curious if there's anyone out there who also has dark blonde hair and has used Green Envy. did it fade well? did your prefered blonde dye cover it up well when you grew tired of it? is there another dark green dye by another brand that you liked better? any information would be so greatly appreciated! :):)
