An accent wall
An accent wall (a.k.a. "feature wall") is a wall whose design differs from the design of the other walls in the room. The accent wall's color can simply be a different shade of the color of the other walls, or have a completely different design in terms of the color and material. The surface of the accent wall can be paint, wallpaper, brick, marble etc. As their name implies, accent walls are typically intended to break up the pattern created by the other walls, especially when the walls are painted a single flat tone. However, a room may be wallpapered and have an accent wall that is untextured and undecorated, as it would serve the same purpose. The point of this can be for aesthetics alone or to highlight or frame some decorative element, such as a painting.
