Find your sofa's undertone first. Warm gray (taupe-leaning) sofas look best with greige, warm whites and earthy accents; cool gray sofas suit crisp whites, blue-grays and greens. Add warm wood, texture and one accent color so the room doesn't feel flat.

Choose a wall color at least one LRV step lighter or deeper than the sofa, and anchor it with a rug that bridges both.
Durable charcoal sofas look great against warm greige with wood and leather accents.
In low light, a warm white or light greige wall keeps a gray sofa from feeling dull.
A gray loveseat with sage or navy walls feels focused and calm.
Warm whites, greiges, gray-greens and navy are reliable. The key is matching the sofa's undertone: warm walls for taupe-gray, cooler or green walls for blue-gray.
Mustard, blush, navy, rust, sage and cognac all work. Choose one or two and repeat them across pillows, art and a rug.
Either works; just avoid the same value. Lighter walls feel airy, while deep walls like navy or green make a light gray sofa stand out.
Add texture, warm wood, a patterned rug and one or two accent colors. Changing the wall from gray to a warm greige or green is often enough.
