Nelson Blue vs Ammonite
Nelson Blue (Benjamin Moore) and Ammonite (Farrow & Ball) come from different manufacturers. Hue-wise, Nelson Blue belongs to the blue-green family and Ammonite to the beige-greige family. The 3-point LRV gap — 69 for Ammonite vs 65 for Nelson Blue — means Ammonite will open up a space more effectively. Where Nelson Blue leans green, Ammonite reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 5.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Nelson Blue vs Ammonite in Real Spaces
3 real rooms side by side. Nelson Blue 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.
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. Ammonite reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Ammonite has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Ammonite has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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