River Silt vs Purbeck Stone
River Silt (Benjamin Moore) and Purbeck Stone (Farrow & Ball) come from different manufacturers. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. The 31-point LRV gap — 52 for Purbeck Stone vs 21 for River Silt — means Purbeck Stone will open up a space more effectively. Where River Silt leans red, Purbeck Stone reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 25.5 puts these firmly in different territory — two distinct design choices rather than close alternatives.

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.
