Opal vs Ammonite
Where Opal belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Opal reads as beige, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. Opal (LRV 84) reflects noticeably more light than Ammonite (LRV 69), a difference of 15 points that becomes especially apparent in rooms with limited natural light. Opal runs red while Ammonite is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 7.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

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.
