Gray has been my go-to neutral for a while now. I find it more crisp and clean looking than ubiquitous beige. But gray lacks the warmth of beige, so try pairing it with warm wood tones or a warm accent hue, such as the yellow-green used here. I recently designed a space layered in different shades of medium to light grays, and it has a supersophisticated vibe. With a base of gray tones in a room, you can add a dash of any other color you want, even beige.
