About Glidden Gunmetal Gray
With an LRV of 14, Gunmetal 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.
Gunmetal Gray works best as a feature — a single wall, built-ins, a study or dining room — rather than wrapping a whole bright space. Grays like this read as a modern neutral and sit comfortably alongside both warm woods and cool metals.
