Horizon Gray vs Purbeck Stone
Where Horizon Gray belongs to Benjamin Moore's range, Purbeck Stone is a Farrow & Ball color. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (51 vs 52), so they'll read as similarly Medium in most lighting conditions. Horizon Gray runs yellow while Purbeck Stone is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.8 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.
Horizon Gray vs Purbeck Stone in Real Spaces
3 real rooms side by side. Horizon Gray 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.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. The distinction reads clearly at room scale, making the choice between them concrete.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Mudroom
Mudrooms are seen in passing, often under whatever light comes through the door — a context that favors colors with some depth. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

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