Celestial vs Mercurial
Celestial and Mercurial come from the same Sherwin-Williams collection. Hue-wise, Celestial belongs to the blue family and Mercurial to the greige-grey family. The 18-point LRV gap — 61 for Mercurial vs 44 for Celestial — means Mercurial will open up a space more effectively. Where Celestial leans cool, Mercurial reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 24.1 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
