Neptune Seas vs Ammonite
Neptune Seas (Dulux) and Ammonite (Farrow & Ball) come from different manufacturers. Neptune Seas reads as blue-grey, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. The 50-point LRV gap — 69 for Ammonite vs 19 for Neptune Seas — means Ammonite will open up a space more effectively. Where Neptune Seas leans cool, Ammonite reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 39.6 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Neptune Seas vs Ammonite in Real Spaces
2 real rooms side by side. Seeing Neptune Seas 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 Neptune Seas.
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 Neptune Seas would.

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.
