Mountain Ash vs Purbeck Stone in Real Spaces
5 real rooms side by side. Mountain Ash 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Purbeck Stone returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that Purbeck Stone will make the room feel meaningfully brighter than Mountain Ash would.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that Purbeck Stone will make the room feel meaningfully brighter than Mountain Ash would.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. Purbeck Stone reflects noticeably more light off the walls, making the space read more open than Mountain Ash.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Purbeck Stone will make the room feel meaningfully brighter than Mountain Ash would.

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.
