Mineral Deposit vs Uncertain Gray
Both from Sherwin-Williams's palette. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (43 vs 43), so they'll read as similarly Medium in most lighting conditions. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. At ΔE 2.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Mineral Deposit vs Uncertain Gray in Real Spaces
2 real rooms side by side. Mineral Deposit and Uncertain 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.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon 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 are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

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