Mouse grey vs Quartz grey

Mouse grey vs Quartz grey in Real Spaces
2 real rooms side by side. Mouse grey and Quartz grey 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.

5 simulated room previews — drag the slider on each to see Mouse grey on one side and Quartz grey 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.
