Luxe Blue vs Mesmerize

Both from Sherwin-Williams's palette. Hue-wise, Luxe Blue belongs to the blue family and Mesmerize to the blue-grey family. They have nearly identical light reflectance values (13 vs 13), 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 5.6 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
