When there's a beautiful fireplace in your living room, you might as well use it as the focal point of your decor. For this modern and sophisticated living room design, a dark navy blue color sets the elements' tone. You'll notice the color spreads across the curtains, patterned area rug, and even on the pillows and throws. It also pairs well with the leather and wooden accents from the furniture pieces. Working with the fireplace as the center of attention, other items like a bar cabinet, floating shelves, mirrors, and wall art can easily be placed next to the fireplace without worrying about being too much. Streamline and clean lines in the furniture pieces, as well as the couches, are what make this living room a sophisticated dream come true.
