Very pale green and diluted purple/pink

So, up until I started to fade my pastel turq, it was a lovely icy blue. I sat with head and shoulders on my hair for an hour and the ends are white, but near the roots turned a pale green. Today I mixed Lush's I love juicy, head and shoulders and baking soda and left it on for an hour. More bits went back to white, the green turned even paler green. It's very light, but it does worry me.

I was planning on diluting crazy color violette and doing a light purple next (that will hopefully fade to more of a pastel colour). But I'm unsure whether the green is a problem. What do you guys think? I can, of course, sit with head and shoulders on my hair for a few times until the dye arrives and I will. But I don't think all the green will come out.

I was also toying with the idea of doing diluted violette, diluted turq and maybe a diluted pink all at once. So if all over isn't an option, I can still do that and dye the green bits over with turq.
