Ammonite vs North Star
Where Ammonite belongs to Farrow & Ball's range, North Star is a Sherwin-Williams color. Ammonite reads as beige-greige, while North Star reads as blue-grey — two distinct hue families, not close cousins. Ammonite (LRV 69) reflects noticeably more light than North Star (LRV 62), a difference of 7 points that becomes especially apparent in rooms with limited natural light. Ammonite runs warm while North Star is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 7.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Ammonite vs North Star in Real Spaces
3 real rooms side by side. Ammonite and North Star 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The brightness difference is modest but present — Ammonite gives the walls a little more lift.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Ammonite reads slightly lighter here — a subtle but real difference in how open the space feels.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Ammonite reads slightly lighter here — a subtle but real difference in how open the space feels.

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