Mountain Moss vs Ammonite
Mountain Moss (Benjamin Moore) and Ammonite (Farrow & Ball) come from different manufacturers. Both sit in the beige-greige family, which is useful context if you're narrowing within a single hue direction. The 51-point LRV gap — 69 for Ammonite vs 18 for Mountain Moss — means Ammonite will open up a space more effectively. Where Mountain Moss leans yellow, Ammonite reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 41.0 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Ammonite returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Ammonite returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Mountain Moss vs Ammonite Simulated Comparison
5 simulated room previews — drag the slider on each to see Mountain Moss 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.
