Gray Mountain vs Dusty grey
Gray Mountain is a Benjamin Moore color while Dusty grey comes from RAL Classic. These are both greys, so the question isn't which hue to choose — it's where within grey to land. At LRV 23 vs 19, Dusty grey will read as the brighter of the two — a 4-point gap that matters most in north-facing or low-light rooms. At ΔE 4.4, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.
