Form vs Tabby Cat Gray in Real Spaces
1 real room side by side. Form and Tabby Cat 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.

5 simulated room previews — drag the slider on each to see Form on one side and Tabby Cat 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.
