Quartz vs Purbeck Stone
Where Quartz belongs to Cloverdale Paint's range, Purbeck Stone is a Farrow & Ball color. Hue-wise, Quartz belongs to the beige-greige family and Purbeck Stone to the greige-grey family. Quartz (LRV 70) reflects noticeably more light than Purbeck Stone (LRV 52), a difference of 18 points that becomes especially apparent in rooms with limited natural light. The ΔE 9.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Quartz vs Purbeck Stone in Real Spaces
5 real rooms side by side. Quartz 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 LRV gap is large enough that Quartz will make the room feel meaningfully brighter than Purbeck Stone would.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Quartz reflects noticeably more light off the walls, making the space read more open than Purbeck Stone.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Quartz reflects noticeably more light off the walls, making the space read more open than Purbeck Stone.
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. Quartz returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Quartz reflects noticeably more light off the walls, making the space read more open than Purbeck Stone.

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