When I had a consultation with you in the fall this is what you reccommended for me to use. I had a little scare and was hesitant to try again. Since then I have used redken 10 (at the salon - did not lift at all) with highlights, schwatzkoph 12-1 with color charm white lady toner ( kinda brassy) ( Is what I had at home and appplied to roots only), and matrix high lift with highlights as well(at salon- this was the best of the three). None of these base colors could compare to the great icey tone I achieved from this mixture. You know your stuff.
