TIP #7: Accent walls
The best way to introduce color onto your walls without committing to all 4 walls, is to paint 1 wall a different color. You can choose your accent wall by seeing which wall is most noticeable in the room – it is usually the wall with a fireplace or a set of beautiful windows or the wall that your bed is up against. These are walls that you look at first when entering a room.
Paint the other walls a neutral, but then find a great color from the fabrics in the room, carpet, artwork, and use that color as your accent wall color. Accent walls add interest and a designer look to the space.
