Guessing at what you mean by “tan”, I will suggest:

B.M. Cumulous Cloud for the walls and B.M.Stone White for the ceiling.

Thank you. Saw your question about vanity or walls...walls, of course but am buying a new vanity top, wondering what color would go best, been looking at Swanstone vanity top in Tahiti desert or white, the vanity base is oak but will consider painting base and if so what color to paint it? I appreciate your help.
