The 36-point LRV gap — 88 for Mountain Air vs 52 for Purbeck Stone — means Mountain Air will open up a space more effectively. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 17.8 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Mountain Air vs Purbeck Stone in Real Spaces
3 real rooms side by side. Seeing Mountain Air and Purbeck Stone in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Mountain Air reflects noticeably more light off the walls, making the space read more open than Purbeck Stone.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Mountain Air 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 Mountain Air will make the room feel meaningfully brighter than Purbeck Stone 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.
