The walls in the living room can either be plain or you can have one accent wall over there. You can paint this wall in some vibrant color other than the rest of the walls and thus make it pop out. Or you can choose to add a different texture on that wall, such as stone or bricks. And yet there is still one more option of making an accent wall with a wall mural. Wall murals can give a new look to the living room, especially the 3D ones.
