Brewster Gray vs Ammonite
Brewster Gray (Benjamin Moore) and Ammonite (Farrow & Ball) come from different manufacturers. Brewster Gray reads as blue-grey, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. The 39-point LRV gap — 69 for Ammonite vs 30 for Brewster Gray — means Ammonite will open up a space more effectively. Where Brewster Gray leans blue, Ammonite reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 26.5 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Brewster Gray vs Ammonite in Real Spaces
5 real rooms side by side. Seeing Brewster Gray 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 Brewster Gray.
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 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Brewster Gray would.
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 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Ammonite returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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