Painting master bath. I would like to do a mid to deep gray pearl faux finish on the bottom and a sophisticated plum or lavender on the top, with a very wide chair rail. The ceilings are very high. The counter is a peachy rose color. There in an inset wall ab ove the toilet that I wold like to paint a very deepbshade of the wall color and then put white shelves.

I need suggestions for the wall color.

The master bedroom is painted BM Atmopsheric, which is an Affinity color.
