Benjamin Moore

Onyx

2133-10

Onyx by Benjamin Moore is a deep, near-total black with slight warm undertones that distinguish it from cooler, more industrial blacks. Its LRV of 4.99 means it absorbs most available light, producing a dense, saturated appearance on walls and trim. This makes it well suited for accent walls, exterior doors, cabinetry, and spaces intended to feel enclosed or dramatic.

It functions as a grounding neutral in both modern and traditional settings. Onyx works well alongside Benjamin Moore's White Dove, Simply White, Kendall Charcoal, Smokey Taupe, and Hale Navy, providing contrast or tonal depth depending on the application.

Onyx in Different Light

Light temperature is measured in Kelvin: a warm 2700K bulb pulls colors toward yellow, while 5000K daylight reads cooler and truer. Check the color at the time of day you actually use the room.

LRV measures how much light a color reflects, from 0 (black) to 100 (pure white). Below about 50 a color needs good lighting to avoid going flat, 60 and up helps brighten a room, and most whites sit above 80.
