Purbeck Stone vs Desert Dune
Purbeck Stone (Farrow & Ball) and Desert Dune (PPG) come from different manufacturers. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. The 10-point LRV gap — 52 for Purbeck Stone vs 42 for Desert Dune — means Purbeck Stone will open up a space more effectively. ΔE 7.5 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 7 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Purbeck Stone vs Desert Dune in Real Spaces
7 real rooms side by side. Purbeck Stone and Desert Dune 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Purbeck Stone reflects noticeably more light off the walls, making the space read more open than Desert Dune.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Purbeck Stone returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Purbeck Stone returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Purbeck Stone will make the room feel meaningfully brighter than Desert Dune would.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Purbeck Stone returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Purbeck Stone returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The LRV gap is large enough that Purbeck Stone will make the room feel meaningfully brighter than Desert Dune would.

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