Crazy color home dye nightmare

I have a on and off again client the has been doing her own color for about a year now. She is a base 6. She has been using a red violet ion shade permanent color from sallys and topping it off with a hodge podge of direct dyes.

Now she wants to go a level 7 turquoise/natural 6 ombre.

I was shocked when I saw her because it looks like the repeated application of the permanent color has really lightened her hair. Maybe to a 9 even, but its hard to tell under all the direct dye.

I plan...
