We suspect that the key to making this room work is how each piece of furniture, no matter what style, is given relevance thanks to color. The Tiffany's-blue walls in the living room perfectly matches the upholstery of the French arm chairs. Then, the mid-century modern red Danish chair in the living room ties beautifully with the bold red and white wallpaper in the dining room, giving us visual cues of how the rooms flow together. Even the different woods are interconnected: the MCM chair and the floor lamp in the corner go together; and the dark wood of the French chairs and ottoman match the dining chairs and table.
