Start with Deep Navy on the walls and the whole room settles down into something calm and grown-up. It is a rich, almost inky blue that reads cozy at night and crisp in daylight, so a living room wrapped in it feels both relaxing and a little dressed up. Navy this deep also makes your art, your books, and the people in the room stand out, which is exactly what you want where everyone gathers.
To keep all that color from feeling heavy, bring in Bright White on the trim, baseboards, and ceiling line. It frames the navy cleanly and bounces light back into the space. Then add small touches of Brass Tan, a soft golden tone that warms the cool blue and ties to brass lamps, picture frames, or a throw pillow. Put the navy on the walls, the white on every edge and molding, and let the brass tan show up in your hardware and small details.
