Breathtaking vs Mercurial

Breathtaking and Mercurial come from the same Sherwin-Williams collection. Hue-wise, Breathtaking belongs to the blue family and Mercurial to the greige-grey family. Their light reflectance values are nearly the same — 63 vs 61 — so neither will read significantly brighter or darker than the other. Where Breathtaking leans cool, Mercurial reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 13.2 puts these firmly in different territory — two distinct design choices rather than close alternatives.
