Warm Pewter vs Uncertain Gray
Warm Pewter is a Dulux color while Uncertain Gray comes from Sherwin-Williams. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. At LRV 43 vs 39, Uncertain Gray will read as the brighter of the two — a 4-point gap that matters most in north-facing or low-light rooms. They share a neutral quality — useful to know if you're layering them in the same space. At ΔE 3.0, 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.
Warm Pewter vs Uncertain Gray in Real Spaces
3 real rooms side by side. Warm Pewter 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
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The brightness difference is modest but present — Uncertain Gray gives the walls a little more lift.
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. Uncertain Gray reads slightly lighter here — a subtle but real difference in how open the space feels.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The brightness difference is modest but present — Uncertain Gray gives the walls a little more lift.

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.
