Portland Gray vs Ammonite
Portland Gray is a Benjamin Moore color while Ammonite comes from Farrow & Ball. Portland Gray reads as greige-grey, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. At LRV 69 vs 60, Ammonite will read as the brighter of the two — a 9-point gap that matters most in north-facing or low-light rooms. The tonal difference — Portland Gray's red character against Ammonite's warm — becomes most visible against white trim or in morning light. At ΔE 4.6, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Portland Gray vs Ammonite in Real Spaces
2 real rooms side by side. Portland Gray and Ammonite 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.
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 Portland Gray.
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 Portland Gray would.

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.
