Copper Clay vs Mars Red

Both from Benjamin Moore's palette. These are both pink-reds, so the question isn't which hue to choose — it's where within pink-red to land. They have nearly identical light reflectance values (11 vs 11), so they'll read as similarly Dark in most lighting conditions. Both lean red, so they'll behave similarly in mixed or changing light conditions. At ΔE 1.8, 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.
