1. If it is a calm style, it is recommended that you choose the same color as the background wall or door, because from my point of view, your floor and wall basically belong to the same color, and the door and the background wall belong to the same color. If you use a sofa in the same color as the door, the door, the sofa and the background wall will become an organic whole, forming a human vision in the living room, and can produce a strong contrast with the wall and the ground, rich Layered. The overall look is harmonious and unified, and it also meets your requirements for a calm and atmospheric style.
