Pink to green back to pink?

Hi guys, I'm hoping someone can help me.
I had originally had been dying my hair red/darkish purple for about a year when I decided I wanted to try a pastel lilac colour so I bleached/toned to the whitest I could and popped a semi permanent pink and purple mixed with a lot of conditioner on it and kept that up for about three months. Last week I decided I wanted to try out a pastel blue so I brought some cheap colour remover (from Savers, I don't remember what it was called, I think it was my provoke?) and I popped that on the pink. It went a bluey green colour as it was developing on my head, and when I washed it off it was a pale green with a little bit of blue. I wasn't too bothered because it was going blue anyway, so I dyed it blue and it came out blue at the top and a bit of a greener/mint tone in the ends.
As the week has passed I've started to miss my pink hair more than I thought I would (it was so pwetty 🙁 ) and I'll be going back to pink in a few weeks, once I've faded the current colour as much as I can.
But, it suddenly occured to me that under the semi-permanent colour I have on at the moment is a greeny icky base, so how on earth can I get it to pink? I've read a few things on the internet and people have bleached their hair from a faded teal colour and used purple shampoo when rinsing the bleach out and it's gone an almost white blonde, which would be ideal for me because I can pop the pink on a fresh, white base colour but I've also seen a lot of things about putting ketchup on green hair to tone it to a 'normal' colour but 1) ketchup is so gross to me, I can barely eat it let alone put it on my head and 2) haven't I stripped all the red tones out of my hair? so what colour would it go if I were to 'replace' the red tones I've taken out? Would I be able to put a golden toned blonde on it to tone it to a ash blonde or would that just be a giant fail? I'm not really sure how I'm going to achieve it.

So, just to sum up.. used a colour remover, hair went green, put a semi-permanent blue on, hair went minty blue, I want to go back to an easier base blonde to go back to my beloved pink colour... help?

Thanks guys  *loveeyes*
