Onyx Technical Profile
What color is Onyx? It's a dark neutral gray with the hex code #363535. Colors similar to Onyx include Hirshfield's Sayward Pine, Sherwin-Williams Black Magic, Farrow & Ball Pitch Black. Onyx has a neutral undertone, which affects how it pairs with trim, flooring, and adjacent wall colors. With an LRV of 4, Onyx creates a dramatic, enveloping mood — best on accent walls, dining rooms, and intimate spaces where atmosphere matters more than reflected light. Onyx 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. 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.
