Ammonite vs Gypsum
Ammonite (Farrow & Ball) and Gypsum (Sherwin-Williams) come from different manufacturers. Hue-wise, Ammonite belongs to the beige-greige family and Gypsum to the white family. The 13-point LRV gap — 82 for Gypsum vs 69 for Ammonite — means Gypsum will open up a space more effectively. Where Ammonite leans warm, Gypsum reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 7.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Ammonite vs Gypsum in Real Spaces
2 real rooms side by side. Ammonite and Gypsum 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Gypsum reflects noticeably more light off the walls, making the space read more open than Ammonite.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Gypsum returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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