About Benjamin Moore 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.
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.
