Yellow orange to neutral light brown

[meaghan_rollo]

At the salon I lighten level 3 dark brown hair to a yellow orange level 7/8 I want to tone out the orange and yellow tones but I dont want it to come out "muddy". Client doesnt mind a little warmth or violet violet tones, just doesnt like the brasiness right now. She also doesnt want to go any darker.
I use matrix color line
