Cumulus Cloud vs Purbeck Stone
Cumulus Cloud is a Benjamin Moore color while Purbeck Stone comes from Farrow & Ball. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. With LRVs of 52 and 52, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Cumulus Cloud's red character against Purbeck Stone's warm — becomes most visible against white trim or in morning light. With a ΔE of 1.3, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cumulus Cloud vs Purbeck Stone in Real Spaces
4 real rooms side by side. Cumulus Cloud and Purbeck Stone are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

5 simulated room previews — drag the slider on each to see Cumulus Cloud 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.
