Ammonite vs Purbeck Stone
Both are Farrow & Ball colors. Hue-wise, Ammonite belongs to the beige-greige family and Purbeck Stone to the greige-grey family. At LRV 69 vs 52, Ammonite will read as the brighter of the two — a 17-point gap that matters most in north-facing or low-light rooms. They share a warm quality — useful to know if you're layering them in the same space. At ΔE 9.3, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Ammonite vs Purbeck Stone in Real Spaces
6 real rooms side by side. Ammonite and Purbeck Stone 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.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Ammonite returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Purbeck Stone would.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Purbeck Stone would.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. Ammonite reflects noticeably more light off the walls, making the space read more open than Purbeck Stone.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Purbeck Stone would.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Purbeck Stone would.

Ammonite vs Purbeck Stone Simulated Comparison
5 simulated room previews — drag the slider on each to see Ammonite on one side and Purbeck Stone 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.
