Gray Matters vs Rare Gray
Both are Sherwin-Williams colors. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. With LRVs of 39 and 38, they'll behave almost identically in terms of how much light they reflect back into a room. They share a neutral quality — useful to know if you're layering them in the same space. With a ΔE of 2.9, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Gray Matters vs Rare Gray in Real Spaces
3 real rooms side by side. Gray Matters and Rare Gray 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.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

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.
