Arsenic vs Aquastone
Where Arsenic belongs to Farrow & Ball's range, Aquastone is a Sherwin-Williams color. Hue-wise, Arsenic belongs to the green family and Aquastone to the blue family. Aquastone (LRV 49) reflects noticeably more light than Arsenic (LRV 37), a difference of 12 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 8.7 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.
