After Midnight vs Soot

Both from Benjamin Moore's palette. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. They have nearly identical light reflectance values (6 vs 6), so they'll read as similarly Dark in most lighting conditions. Both lean blue, so they'll behave similarly in mixed or changing light conditions. At ΔE 1.9, 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.
