Gossamer Blue vs Ammonite
Where Gossamer Blue belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Gossamer Blue reads as blue, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. Ammonite (LRV 69) reflects noticeably more light than Gossamer Blue (LRV 55), a difference of 14 points that becomes especially apparent in rooms with limited natural light. Gossamer Blue runs blue while Ammonite is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 12.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Gossamer Blue vs Ammonite in Real Spaces
4 real rooms side by side. Seeing Gossamer Blue 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Gossamer Blue would.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Ammonite reflects noticeably more light off the walls, making the space read more open than Gossamer Blue.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Ammonite reflects noticeably more light off the walls, making the space read more open than Gossamer Blue.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Ammonite reflects noticeably more light off the walls, making the space read more open than Gossamer Blue.

5 simulated room previews — drag the slider on each to see Gossamer 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.
