Looking for the best color to paint the room(s). The kitchen wall extends into the living room, so it will need to be the same color. Upper cabinets/countertops are white; lower cabinets stainless steel (although they look darker in the picture). Floor is a light beige tile; design tends toward mid century modern. The opposite wall is all windows, so tons of natural light. Thinking of a gray, but I always struggle with gray looking different once on the walls. If anyone has a gray (or other color) suggestion, would be very helpful. Picture is for info only; home is now empty
