Guild Grey vs On The Rocks
Guild Grey and On The Rocks come from the same Sherwin-Williams collection. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 63 vs 62 — so neither will read significantly brighter or darker than the other. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 1.1 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Guild Grey vs On The Rocks in Real Spaces
1 real room side by side. Guild Grey 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

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.
