Blue Iris vs Mercurial
Both from Sherwin-Williams's palette. Hue-wise, Blue Iris belongs to the blue-grey family and Mercurial to the greige-grey family. Blue Iris (LRV 73) reflects noticeably more light than Mercurial (LRV 61), a difference of 12 points that becomes especially apparent in rooms with limited natural light. Blue Iris runs neutral while Mercurial is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 7.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

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.
