Icy vs Mercurial

Icy and Mercurial come from the same Sherwin-Williams collection. Icy reads as blue, while Mercurial reads as greige-grey — two distinct hue families, not close cousins. The 5-point LRV gap — 61 for Mercurial vs 56 for Icy — means Mercurial will open up a space more effectively. Where Icy leans cool, Mercurial reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 11.1 puts these firmly in different territory — two distinct design choices rather than close alternatives.
