Mansard Stone works as a warm neutral anchor — pairs cleanly with most existing palettes and reads forgiving across lighting conditions. At LRV 21 it reads as a deep, enveloping shade — best on accent walls, dining rooms, and spaces where atmosphere matters more than reflected light. Skip it if you want a crisp, cool-modern look, or in rooms with heavy north light that can pull its warmth slightly muddy.

What color is PPG Mansard Stone (30YY 20/029)? It's a deep warm gray — hex #817E7A, LRV 21. The closest cross-brand equivalent to Mansard Stone is Behr Greyhound — a near-identical match on the wall, with Benjamin Moore Barnwood and Sherwin-Williams Going Grey also close. With an LRV of 21, Mansard Stone creates a dramatic, enveloping mood — best on accent walls, dining rooms, and intimate spaces where atmosphere matters more than reflected light. As a warm neutral, Mansard Stone pairs with off-whites for trim, white oak or walnut floors, and brass or warm brushed nickel hardware. Deep green, navy, or terra-cotta all read well as accent colors. As a deeper neutral, Mansard Stone reads as a confident anchor — strongest on accent walls, cabinetry, and moody whole rooms that get enough natural light to keep it from going flat. Warm neutrals come alive under 2700K bulbs, where their underlying yellow or peach undertones add visible warmth. Under 4000K daylight they read cleaner and slightly cooler. Deeper neutrals can read close to black in low light, so preview Mansard Stone in the room's actual evening lighting, not just at midday.
