Chiswell Blue vs Gothic Arch

Chiswell Blue and Gothic Arch come from the same Benjamin Moore collection. Hue-wise, Chiswell Blue belongs to the blue-grey family and Gothic Arch to the greige-grey family. Their light reflectance values are nearly the same — 30 vs 31 — so neither will read significantly brighter or darker than the other. Where Chiswell Blue leans blue, Gothic Arch reads red — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 14.2 puts these firmly in different territory — two distinct design choices rather than close alternatives.
