Start with Soft Gray on the walls. It is a gentle, warm-leaning gray that wraps a living room in quiet without feeling flat or chilly. It plays nicely with daylight and lamplight, holds its calm next to almost any sofa, and gives you a relaxed backdrop you will not get tired of. This is the color that makes the room feel settled and easy to live in.
Then bring in Crisp White on the trim and ceiling to keep the edges clean and the whole space feeling fresh. Finally, add Golden Yellow as your spark, just in small doses through pillows, a throw blanket, or a single accent piece. So: Soft Gray on the walls, Crisp White on the trim, and a few hits of Golden Yellow to make the room feel sunny and alive.
