When you're getting ready to sell your home isn't the time to see how much "fun" a particular color could be on the walls. You don't want to create an interesting new look that potential buyers may really hate. Instead, focus on rich neutrals like mocha, beige, and shades of gray. These can create a backdrop that's very sophisticated and appealing to almost any buyer. You don't need to paint everything white to stay neutral, but you do need to keep things like and classic.
