Rust vs Ammonite
Rust (Benjamin Moore) and Ammonite (Farrow & Ball) come from different manufacturers. Rust reads as beige-pink, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. The 49-point LRV gap — 69 for Ammonite vs 20 for Rust — means Ammonite will open up a space more effectively. Where Rust leans red, Ammonite reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 55.1 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Rust vs Ammonite in Real Spaces
1 real room side by side. Seeing Rust and Ammonite in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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 reflects noticeably more light off the walls, making the space read more open than Rust.

Rust vs Ammonite Simulated Comparison
5 simulated room previews — drag the slider on each to see Rust 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.
