Ammonite vs Grey Heron
Where Ammonite belongs to Farrow & Ball's range, Grey Heron is a Sherwin-Williams color. Ammonite reads as beige-greige, while Grey Heron reads as greige-grey — two distinct hue families, not close cousins. Ammonite (LRV 69) reflects noticeably more light than Grey Heron (LRV 65), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. At ΔE 2.3, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.

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.
