I just moved into a shotgun house and I want to paint the rooms hues of gray. I want the living room to be light gray. From the living room, you can see the my bedroom and my daughter's bedroom. I read that the rooms you can see from the front of the house must flow with each other. I was thinking about making the bedroom gray with blue undertone and my daughter's room gray with purple undertone. Can you guys help me find some paint colors that you think would make the rooms flow and not seem so choppy but not so bland also?
