MercurialSherwin-WilliamsvsWindy BlueSherwin-WilliamsΔE 14.3 — Distinct difference

Both from Sherwin-Williams's palette. Mercurial reads as greige-grey, while Windy Blue reads as blue — two distinct hue families, not close cousins. Mercurial (LRV 61) reflects noticeably more light than Windy Blue (LRV 48), a difference of 13 points that becomes especially apparent in rooms with limited natural light. Mercurial runs warm while Windy Blue is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 14.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
