Gloucester Sage vs Sage Mountain
Both from Benjamin Moore's palette. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. Sage Mountain (LRV 29) reflects noticeably more light than Gloucester Sage (LRV 19), a difference of 9 points that becomes especially apparent in rooms with limited natural light. Both lean yellow, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 10.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
