What Is Benjamin Moore Onyx?
Benjamin Moore Onyx is one of the darkest colors in the BM residential line and one of the closest the brand comes to a pure, neutral black. The slight warmth in the undertone prevents it from reading as cold or harsh in most spaces, which is why it’s frequently specified for front doors, cabinets, and exterior trim where a bold, definitive black is the goal without the stark quality of a fully neutral true black.
Onyx in different lighting:
- In natural daylight: reads as a deep, rich black with minimal perceptible undertone
- In warm artificial light (incandescent, warm LED): the slight warmth becomes more visible, keeping the color from feeling cold
- In cool artificial light: reads very close to neutral black, minimal shift
- On exteriors in direct sun: maintains depth without the green shift sometimes seen with SW Iron Ore
What Onyx works best on:
- Front doors (one of BM’s most-specified door colors)
- Kitchen cabinets and islands — the slight warmth prevents the harsh contrast that cooler blacks can create against warm wood flooring and hardware
- Exterior trim on white or light-colored homes
- Interior accent walls in spaces with warm-toned furnishings
- Built-ins and shelving units
What pairs well with BM Onyx:
- BM Chantilly Lace (OC-65) — crisp cool white for trim contrast
- BM White Dove (OC-17) — warmer white that bridges naturally with Onyx’s slight warmth
- Natural wood tones, aged brass, and matte black hardware
- Warm neutral walls: Benjamin Moore Pale Oak (OC-20), Edgecomb Gray (HC-173)
What is Benjamin Moore Black Beauty
Benjamin Moore Black Beauty is one step up from Onyx in the BM lineup, measurably lighter at LRV 5 and carrying a more noticeable blue undertone that gives it a cooler, more charcoal quality. In rooms or on surfaces where a true black would feel too heavy, Black Beauty provides a near-black depth while remaining slightly more approachable.
The blue undertone makes Black Beauty a natural fit for spaces with cool-toned materials: white marble, polished chrome, cool gray flooring. On south-facing exterior walls with significant sun exposure, the blue cast can shift perceptibly, which is worth sampling before committing to a large exterior application.
What Black Beauty works best on:
- Contemporary and modern kitchen cabinets where a cool charcoal reads more intentional than a warm black
- Exterior trim on homes with cool stone or concrete elements
- Interior doors in modern spaces
- Accent walls in cool-toned rooms

From Our Experience in Fairfax
We paint front doors, cabinets, and exterior trim with BM Onyx regularly across Fairfax and Northern Virginia homes. It’s one of the most consistently requested dark colors we work with, and for good reason, it’s reliably neutral enough to suit a wide range of architectural styles and interior palettes without the undertone variability that makes some other near-blacks harder to work with.
The most common decision point we help homeowners navigate is Onyx vs. Black Beauty. On warm-toned kitchens with wood floors and brass or oil-rubbed bronze hardware, Onyx almost always reads better, the slight warmth keeps the cabinets from feeling cold and disconnected. In modern kitchens with concrete countertops, polished chrome, and cooler-toned materials, Black Beauty’s blue cast integrates more naturally.
For front doors in Northern Virginia’s climate, which sees significant temperature swings between summer heat and winter freeze-thaw cycles, we use Benjamin Moore Advance or Grand Entrance depending on the door material. Standard interior paint on a front door in this climate shows wear significantly faster than a purpose-built door formula.
