Onyx White vs Ammonite
Where Onyx White belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Hue-wise, Onyx White belongs to the beige-white family and Ammonite to the beige-greige family. Onyx White (LRV 77) reflects noticeably more light than Ammonite (LRV 69), a difference of 8 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. 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.
