Wella Illumina and pastel developer?

[Jules79]

I tried wella 6/16 and wella pastel developer 1:2 and the hair barely changed. The hair was bleached to a level 7/8 And brassy I thought 6/16 would be perfect. Should I have used color touch?

The pastel developer is designed for 9 and 10 range .
It cancels the ammonia out so there's no lift while toning .
I think the colour touch emulsion works good with illimina .
