What color is Benjamin Moore Onyx?

Benjamin Moore Onyx 2133-10 is a near-black charcoal with a restrained, almost neutral cast rather than a flat pure black. Its #353434 value gives it a softened black appearance, with only the faintest suggestion of warmth from the slightly higher red content. In bright daylight, Onyx reads as a deep charcoal; at night or in shadow, it can appear nearly black. It makes a strong choice for interior doors, window trim, built-in cabinetry, or a single accent wall where crisp contrast is wanted without the starkness of absolute black. Pair it with clean whites, pale oak, warm brass, matte black hardware, or light gray stone to let its depth stand out.

What are Benjamin Moore Onyx undertones?

Onyx is a very deep, low-saturation black that reads close to neutral in the supplied digital sample. Any visible red bias is extremely slight, so the sample does not support a confident, distinct undertone call. Benjamin Moore describes Onyx as a deep black that is “luxurious and grounded,” rather than naming a specific undertone. Warm artificial light may make its faint red-leaning cast a little more noticeable, while cool daylight can keep it looking more straightforwardly neutral-black.

LRV of Onyx

Onyx has an LRV of 4.99% and refers to Dark colors which means that this color almost does not reflect light. Why LRV is important?

Light Reflectance Value scale illustration

Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).

Act like a pro: When choosing paint with an LRV of 4.99%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft² living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
