Onyx Black is a true neutral — the rare paint color that doesn't push warm or cool, which makes it forgiving across mixed-lighting rooms and existing palettes. At LRV 4 it reads as a deep, enveloping shade — best on accent walls, dining rooms, and spaces where atmosphere matters more than reflected light. Skip it only if you specifically want a clear warm or cool bias — a true neutral stays intentionally undecided, which is the whole point.

Onyx Black Technical Profile
What color is PPG Onyx Black (00NN 05/000)? It's a dark neutral gray — hex #3C3B3C, LRV 4. The closest cross-brand equivalent to Onyx Black is Behr Limousine Leather — a near-identical match on the wall, with Dunn-Edwards Black and Dunn-Edwards Black also close. With an LRV of 4, Onyx Black creates a dramatic, enveloping mood — best on accent walls, dining rooms, and intimate spaces where atmosphere matters more than reflected light. Onyx Black is a true neutral — pair with any wood, any metal, any trim color. Off-white trim works in most homes; brushed nickel or matte black hardware both read well across spaces. As a deeper neutral, Onyx Black 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. True neutrals read consistently across lighting conditions, which is why they're popular base colors. They inherit a faint warm cast under 2700K and a cool cast under 4000K, but never dramatically. Deeper neutrals can read close to black in low light, so preview Onyx Black in the room's actual evening lighting, not just at midday.
