Ammonite vs S 2005-Y40R
Ammonite (Farrow & Ball) and S 2005-Y40R (NCS) 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 16-point LRV gap — 69 for Ammonite vs 53 for S 2005-Y40R — means Ammonite will open up a space more effectively. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 10.4 puts these firmly in different territory — two distinct design choices rather than close alternatives.

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.
