Balancing Oranges And Blues

There are a couple of places where the shadow color on white (whether it's the blouse or the curtains) is influenced by either the peachy color of the walls or the bluish light coming in the window. So I'm trying to create greys using those colors. The French Ultramarine seems to be working better than the regular ultramarine; meanwhile, that shadowy area to the right f the figure needs to go darker.
