Astronomical vs Ammonite
Astronomical is a Behr color while Ammonite comes from Farrow & Ball. Hue-wise, Astronomical belongs to the grey family and Ammonite to the beige-greige family. At LRV 69 vs 7, Ammonite will read as the brighter of the two — a 62-point gap that matters most in north-facing or low-light rooms. The tonal difference — Astronomical's green character against Ammonite's warm — becomes most visible against white trim or in morning light. At ΔE 55.3, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Astronomical vs Ammonite in Real Spaces
2 real rooms side by side. Seeing Astronomical 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.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Astronomical would.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Astronomical would.

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