Mountain Olive vs Purbeck Stone
Mountain Olive (Behr) and Purbeck Stone (Farrow & Ball) 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 40-point LRV gap — 52 for Purbeck Stone vs 12 for Mountain Olive — means Purbeck Stone will open up a space more effectively. Where Mountain Olive leans yellow, Purbeck Stone reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 36.3 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Mountain Olive vs Purbeck Stone in Real Spaces
4 real rooms side by side. Seeing Mountain Olive 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.
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.
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 Mountain Olive 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.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Purbeck Stone returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
