I would suggest a blue-gray tone for the bedroom. It's a bit warmer then true gray and very peaceful. You can also mix true gray in as accents like gray pillows or a peice of furniture painted gray. Look up some blue gray Benjamin Moore colors like Beacon Gray, Harbor Haze, Silver Gray or November Skies. Put the names of these colors right into the Houzz search bar to see pictures of them! Good luck!

This is BM Mineral Ice and I love the soothing feeling of it
