Ammonite vs Windchill
Ammonite (Farrow & Ball) and Windchill (Sherwin-Williams) come from different manufacturers. Ammonite reads as beige-greige, while Windchill reads as grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 69 vs 68 — so neither will read significantly brighter or darker than the other. Where Ammonite leans warm, Windchill reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 5.1 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Ammonite vs Windchill Simulated Comparison
5 simulated room previews — drag the slider on each to see Ammonite on one side and Windchill 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.
