Jet Black vs Ammonite
Where Jet Black belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Jet Black reads as grey, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. Ammonite (LRV 69) reflects noticeably more light than Jet Black (LRV 5), a difference of 64 points that becomes especially apparent in rooms with limited natural light. Jet Black runs blue and purple while Ammonite is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 65.5, 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 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

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 Jet Black would.
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 Jet Black.

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.
