Koleston mixing

[krnjon]

Could someone possibly help me out
I use 7.0 in koleston I have blonde highlights
What iam struggling with is i am 100% grey I find the 7.0 on my roots a bit flat and light
But find 6.0 to dark
Any suggestion what shades I can use to get the perfect shade
Really would appreciate any advice given
