Schwarzkopf help

Hey. So my cousin has so much black hair dye in , done a strand test and lifted to a level 4 red . What colour would I put on if I wanted to make it a brown with no red ? Would it be a 4 with Matt in ? The green tone ?

Yes I'd use 3.5g 0/22 for every 30g of 4/0

Is there much re-growth? What’s the natural level?
I’d probably remove the black colour first and take it from there.
