I would go to Home Depot or my local paint store for ideas - it all depends on your furniture, floor and decor colors. Grays and neutrals are always popular and Behr and Sherwin Paints have websites you can look at your room shape with colors you pick out
Hi, if it is bare dry wall, you will need to match the texture on the other walls. then prime and paint. you can do an accent color on 1 wall, and leave the rest neutral color.
Kassandra: Maybe these will help
I still love doing high contrast accent walls. I have two jet black accent walls and the rest of the walls are light gray. A lot of people do patterned wood accent walls too, but they seem like a pain to clean to me.
