Black Locust reads as crisp and architectural — strong in modern spaces, with natural fixed elements (chrome, stone, glass), or as a quiet anchor. At LRV 13 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 cozy, warm room — cool neutrals can feel sterile under warm bulbs or in low light.

What color is Behr Black Locust (PPU25-02)? It's a deep cool gray — hex #646763, LRV 13.

With an LRV of 13, Black Locust creates a dramatic, enveloping mood — best on accent walls, dining rooms, and intimate spaces where atmosphere matters more than reflected light.

As a deeper neutral, Black Locust 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.

Deeper neutrals can read close to black in low light, so preview Black Locust in the room's actual evening lighting, not just at midday.
