Cast Iron vs Grey Blue in Real Spaces
1 real room side by side. Cast Iron and Grey Blue 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 Cast Iron on one side and Grey Blue 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.
