Key Lime vs Ammonite
Key Lime (Benjamin Moore) and Ammonite (Farrow & Ball) come from different manufacturers. Key Lime reads as green-yellow, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 71 vs 69 — so neither will read significantly brighter or darker than the other. Where Key Lime leans green, Ammonite reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 32.7 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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