Quixotic Plum vs Sea Mariner
Both from Sherwin-Williams'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 7), so they'll read as similarly Dark in most lighting conditions. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 5.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.
