Jasper Opal vs Ammonite
Jasper Opal (Benjamin Moore) and Ammonite (Farrow & Ball) come from different manufacturers. Jasper Opal reads as beige-yellow, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. The 12-point LRV gap — 81 for Jasper Opal vs 69 for Ammonite — means Jasper Opal will open up a space more effectively. Where Jasper Opal leans yellow, Ammonite reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 19.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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