Grey Heron vs Mercurial
Grey Heron and Mercurial come from the same Sherwin-Williams collection. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. The 4-point LRV gap — 65 for Grey Heron vs 61 for Mercurial — means Grey Heron will open up a space more effectively. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 2.3 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Grey Heron vs Mercurial Simulated Comparison
5 simulated room previews — drag the slider on each to see Grey Heron on one side and Mercurial on the other.
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.
