Mountain Mist vs Ammonite
Where Mountain Mist belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Hue-wise, Mountain Mist belongs to the blue-grey family and Ammonite to the beige-greige family. They have nearly identical light reflectance values (71 vs 69), so they'll read as similarly Light in most lighting conditions. Mountain Mist runs green and blue while Ammonite is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 6.6 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

5 simulated room previews — drag the slider on each to see Mountain Mist 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.
