Deep Onyx Technical Profile
What color is Deep Onyx? It's a dark neutral gray with the hex code #242322. Colors similar to Deep Onyx include MPC Blackguard, RAL Black Brown, Vista Paint Silent Sea. Deep Onyx has a neutral undertone, which affects how it pairs with trim, flooring, and adjacent wall colors. With an LRV of 2, Deep Onyx creates a dramatic, enveloping mood — best on accent walls, dining rooms, and intimate spaces where atmosphere matters more than reflected light. Deep 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.
