An accent wall is a wall in a room that is painted or decorated differently from the other walls in the room. It is used to draw attention to a specific area or feature in the room, such as a fireplace or a piece of artwork. An accent wall can also be used to add color or texture to a room, or to create a focal point that helps to define the room's overall design. Additionally, accent wall can be great ways to make a room look larger or taller, as it can help to break up a large or boxy space, or to add height to a low ceiling.
