how to get apricot/peach from pink and orange

Hi everyone!

I used to have a black and white cruella (as you can see in my userpic) and now I'm trying to get my hair to an even toned pale apricot/peachy pink all over. Because the two sides of my hair started out very different colours and are in very different conditions, I've ended up with one half pastel pink and one half pastel orange, when, what I ideally want is both of them somewhere in between the two. The pink is on the formerly white side and the orange is on the formerly black side. The formerly black side is in worse condition as to some extent I just had to over bleach it a bit because it was taking forever, it's honestly been a year and I'm still not blonde on that side yet!

I'm aiming for something like

and what I have right now is - so it's basically there, it just needs evening out. I've been using a conditioner diluted  mixture of directions mandarin and directions carnation. Was thinking I might try putting just dilet pink on the orange side and just diluted orange on the pink side, do you think that will work? Any advice on how to even the two out without bleaching my darker side further and damaging it more much appreciated!
