Grey Mist vs Sanctuary
Both are Sherwin-Williams colors. Both sit in the beige-greige family, which is useful context if you're narrowing within a single hue direction. With LRVs of 75 and 76, they'll behave almost identically in terms of how much light they reflect back into a room. They share a warm quality — useful to know if you're layering them in the same space. With a ΔE of 1.2, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Grey Mist vs Sanctuary in Real Spaces
4 real rooms side by side. Grey Mist and Sanctuary 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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
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.

Grey Mist vs Sanctuary Simulated Comparison
5 simulated room previews — drag the slider on each to see Grey Mist on one side and Sanctuary 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.
