Best Rooms and Uses for Smoke Gray

Smoke Gray works best as a feature — a single wall, built-ins, a study or dining room — rather than wrapping a whole bright space. Blues calm a room, which makes them popular in bedrooms, bathrooms and home offices.

Light by light

How Lighting Changes Smoke Gray

With an LRV of 21, Smoke Gray is a deep, dramatic shade. It soaks up light in north-facing rooms and looks richest where strong daylight hits it. Because it carries almost no measurable hue, it stays a true neutral and pairs cleanly with nearly any trim or floor. Warm artificial light softens it; cool LED can make it look flat, so match your bulbs to the mood you want.

Test it in your light, not a showroom's

Most complaints about Smoke Gray are a light mismatch. Upload a photo of your actual room and see it on your walls — then ask for the same wall in north light or evening lamps before you buy a single sample.
