Coastal Fog vs Purbeck Stone
Where Coastal Fog belongs to Benjamin Moore's range, Purbeck Stone is a Farrow & Ball color. Coastal Fog reads as beige-greige, while Purbeck Stone reads as greige-grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (53 vs 52), so they'll read as similarly Medium in most lighting conditions. Coastal Fog runs yellow while Purbeck Stone is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 5.6 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Coastal Fog vs Purbeck Stone in Real Spaces
3 real rooms side by side. Coastal Fog 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. The distinction reads clearly at room scale, making the choice between them concrete.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. The distinction reads clearly at room scale, making the choice between them concrete.

Coastal Fog vs Purbeck Stone Simulated Comparison
5 simulated room previews — drag the slider on each to see Coastal Fog 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.
