When should you paint or paper a wall different from other walls? The quick answer is: when you want that wall to stand out. Just make sure that you really want it to stand out. When a wall is a different color or texture from the other walls, your eyes will definitely jump to it. That isn’t a bad thing: in decorating, you want to give a room enough interest that your eyes travel around the room and rest for a few seconds on everything. But just make sure that it’s cohesive. Everything should flow together. If there is nothing else to tie the accent wall to the rest of the room, it will just look odd.
