Blue Gray vs Purbeck Stone
Both from Farrow & Ball's palette. Hue-wise, Blue Gray belongs to the blue-greige family and Purbeck Stone to the greige-grey family. Purbeck Stone (LRV 52) reflects noticeably more light than Blue Gray (LRV 45), a difference of 7 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. The ΔE 6.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Gray vs Purbeck Stone in Real Spaces
4 real rooms side by side. Blue 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.
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. The brightness difference is modest but present — Purbeck Stone gives the walls a little more lift.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Purbeck Stone reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Purbeck Stone reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Purbeck Stone reads slightly lighter here — a subtle but real difference in how open the space feels.

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