Ammonite vs Acanthus
Where Ammonite belongs to Farrow & Ball's range, Acanthus is a Sherwin-Williams color. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. Ammonite (LRV 69) reflects noticeably more light than Acanthus (LRV 60), a difference of 9 points that becomes especially apparent in rooms with limited natural light. Ammonite runs warm while Acanthus is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 9.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Ammonite vs Acanthus in Real Spaces
4 real rooms side by side. Ammonite and Acanthus 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 LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Acanthus would.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Ammonite reflects noticeably more light off the walls, making the space read more open than Acanthus.
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 reflects noticeably more light off the walls, making the space read more open than Acanthus.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Ammonite reflects noticeably more light off the walls, making the space read more open than Acanthus.

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