Where Ammonite leans warm, Iron Grey reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes.

5 simulated room previews — drag the slider on each to see Ammonite on one side and Iron 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.
