Comet vs Purbeck Stone
Comet (Benjamin Moore) and Purbeck Stone (Farrow & Ball) come from different manufacturers. Comet reads as blue-grey, while Purbeck Stone reads as greige-grey — two distinct hue families, not close cousins. The 16-point LRV gap — 52 for Purbeck Stone vs 36 for Comet — means Purbeck Stone will open up a space more effectively. Where Comet leans blue, Purbeck Stone reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 17.4 puts these firmly in different territory — two distinct design choices rather than close alternatives.

5 simulated room previews — drag the slider on each to see Comet on one side and Purbeck Stone on the other.
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.
