Keystone Gray vs Moth Wing
Keystone Gray and Moth Wing 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. Their light reflectance values are nearly the same — 29 vs 29 — so neither will read significantly brighter or darker than the other. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 2.5 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Keystone Gray vs Moth Wing in Real Spaces
3 real rooms side by side. Keystone Gray and Moth Wing 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.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

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.
