hi all, I have been through the many posts on grey toners but I am failing miserably! I've tried a few different wella colours , I've tried mixing 10/0 with a dash of 2/0 , I've tried a few different ash / violet / pearl colour touch toners, I've tried the crazy colour grey and the crazy colour grey with a touch a black but I keep ending up blue !! I'll attach s pic of he latest one I've tried - 10/0 + 2/0. Any advice pleaaseeeeee
