Olympus Green vs Ammonite
Where Olympus Green belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Olympus Green reads as blue-green, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. Ammonite (LRV 69) reflects noticeably more light than Olympus Green (LRV 9), a difference of 59 points that becomes especially apparent in rooms with limited natural light. Olympus Green runs blue while Ammonite is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 52.9, 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.
Olympus Green vs Ammonite in Real Spaces
2 real rooms side by side. Seeing Olympus Green 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 Olympus Green 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 Olympus Green.

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.
