Best crazy colour for toner?

So I'm planning to do bleach baths to get my hair to a medium golden blonde.
During the awkward between stages I wanted to use a toner to reduce the unwanted tones.
I did a strand test, and it came out quite orange, although it had a few yellow tones too. I then used diluted rockabilly blue to tone it down, but the yellow parts turned green.
Should I just use a violet toner instead or should I mix blue and violet to get an in between colour?
Also, what violet semi should I buy? Unfortunately, at the moment I only have access to crazy colour, so for the time being I'll have to go for one of those colours (otherwise I'd buy something like pravana violet). My initial thought was to buy cc violette - is that a good choice, or is it too blue? I also looked at cc hot purple, but if it fades to pink I'm worried it will just make my hair look more orange/coraly. What do you recommend? I'd also consider trying a different brand of toner (rather than one made by mixing semis), as long as I can get hold of it from Sally's/Boots/SuperDrug. Thanks!
