Hibernate vs Keystone Gray
Both are Sherwin-Williams colors. Hue-wise, Hibernate belongs to the grey family and Keystone Gray to the greige-grey family. At LRV 38 vs 29, Hibernate will read as the brighter of the two — a 9-point gap that matters most in north-facing or low-light rooms. The tonal difference — Hibernate's neutral character against Keystone Gray's warm — becomes most visible against white trim or in morning light. At ΔE 8.6, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Hibernate vs Keystone Gray in Real Spaces
3 real rooms side by side. Hibernate and Keystone 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.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. Hibernate reflects noticeably more light off the walls, making the space read more open than Keystone Gray.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Hibernate will make the room feel meaningfully brighter than Keystone Gray would.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The LRV gap is large enough that Hibernate will make the room feel meaningfully brighter than Keystone Gray would.

Hibernate vs Keystone Gray Simulated Comparison
5 simulated room previews — drag the slider on each to see Hibernate on one side and Keystone Gray 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.
