Start with Warm Gray on the walls. It is a gentle greige that feels calm and grown-up without going cold, and it gives a living room that easy, settled backdrop you can live with for years. Because it leans a touch warm, the whole room feels relaxed the moment you walk in, and it lets your furniture and art do the talking.
For the woodwork, Soft White keeps the trim and ceiling light and clean so the gray never feels heavy. Then comes the fun part: a few hits of Golden Mustard as your accent. A mustard chair, a pillow, or a piece of art brings that warm retro glow and a little personality. So in practice it is gray on the walls, soft white on the trim, and mustard saved for the small bold moments.
