About Benjamin Moore Thundercloud Gray
At LRV 50, Thundercloud Gray is a light color that bounces daylight around a room without tipping into stark white. Because it carries almost no measurable hue, it stays a true neutral and pairs cleanly with nearly any trim or floor. It holds its undertone in most exposures, which is what makes light shades like this so forgiving room to room.
Thundercloud Gray is an easy whole-room color for living spaces and bedrooms, and light enough to carry onto trim or a ceiling if you want a soft, seamless look. Grays like this read as a modern neutral and sit comfortably alongside both warm woods and cool metals.
