Ammonite vs S 2005-G10Y
Where Ammonite belongs to Farrow & Ball's range, S 2005-G10Y is a NCS color. Ammonite reads as beige-greige, while S 2005-G10Y reads as green-grey — two distinct hue families, not close cousins. Ammonite (LRV 69) reflects noticeably more light than S 2005-G10Y (LRV 53), a difference of 16 points that becomes especially apparent in rooms with limited natural light. Ammonite runs warm while S 2005-G10Y is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 9.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Ammonite vs S 2005-G10Y in Real Spaces
1 real room side by side. Ammonite and S 2005-G10Y are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.

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.
