Gull Wing Gray vs S 3005-B20G
Gull Wing Gray (Benjamin Moore) and S 3005-B20G (NCS) come from different manufacturers. 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 — 42 vs 40 — so neither will read significantly brighter or darker than the other. Where Gull Wing Gray leans blue, S 3005-B20G reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 2.0 puts them in subtle territory — distinguishable in direct comparison, less so from across a room.
