Grey Heron vs On The Rocks
Both are Sherwin-Williams colors. Hue-wise, Grey Heron belongs to the greige-grey family and On The Rocks to the grey family. At LRV 65 vs 62, Grey Heron will read as the brighter of the two — a 3-point gap that matters most in north-facing or low-light rooms. The tonal difference — Grey Heron's warm character against On The Rocks's neutral — becomes most visible against white trim or in morning light. With a ΔE of 2.0, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Grey Heron vs On The Rocks in Real Spaces
1 real room side by side. Grey Heron and On The Rocks are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Grey Heron has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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