Ammonite vs Blue Grotto
Where Ammonite belongs to Farrow & Ball's range, Blue Grotto is a Sherwin-Williams color. Ammonite reads as beige-greige, while Blue Grotto reads as blue — two distinct hue families, not close cousins. Blue Grotto (LRV NaN) reflects noticeably more light than Ammonite (LRV 69), a difference of NaN points that becomes especially apparent in rooms with limited natural light. Ammonite runs warm while Blue Grotto is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of NaN, 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 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Ammonite vs Blue Grotto in Real Spaces
5 real rooms side by side. Seeing Ammonite and Blue Grotto 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 temperature contrast between Ammonite and Blue Grotto is what sets these apart most in this context.
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 brings more warmth to the space, while Blue Grotto keeps things cooler and crisper.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Ammonite brings more warmth to the space, while Blue Grotto keeps things cooler and crisper.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Blue Grotto reads more restrained here, while Ammonite adds a sense of enclosure and warmth.
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 brings more warmth to the space, while Blue Grotto keeps things cooler and crisper.

5 simulated room previews — drag the slider on each to see Ammonite on one side and Blue Grotto 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.
