Gibraltar vs Mesmerize

Gibraltar and Mesmerize come from the same Sherwin-Williams collection. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Their light reflectance values are nearly the same — 14 vs 13 — so neither will read significantly brighter or darker than the other. Where Gibraltar leans neutral, Mesmerize reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 9.2 means they're clearly different, but not dramatically so — they'd pair well in the same room.
