Mouse grey vs Pewter Green in Real Spaces
3 real rooms side by side. Mouse grey and Pewter Green 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

Kitchen

Mouse grey vs Pewter Green Simulated Comparison
5 simulated room previews — drag the slider on each to see Mouse grey on one side and Pewter Green 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.
