Himalayan Trek vs Shale

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. Shale (LRV 50) reflects noticeably more light than Himalayan Trek (LRV 47), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Both lean red, so they'll behave similarly in mixed or changing light conditions. At ΔE 2.1, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.
