Atrium White vs Ammonite
Where Atrium White belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Both sit in the beige-greige family, which is useful context if you're narrowing within a single hue direction. Atrium White (LRV 85) reflects noticeably more light than Ammonite (LRV 69), a difference of 16 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 8.1 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.
