The Analysis
Onyx is a true, saturated black that absorbs almost all light rather than reflecting it. Because of its very low LRV (3.46), it will make a room feel smaller and more enclosed, which is perfect for creating a cozy, intimate atmosphere.
Onyx works best as a deliberate design statement rather than a neutral backdrop. It is ideal for accent walls, built-in cabinetry, or powder rooms where you want to create a high-contrast focal point.
LRV 3History & Origin
While black has been used in historic interiors for centuries, Onyx feels distinctly modern and sharp. It sheds the stuffiness of traditional dark rooms by providing a clean, contemporary edge.
How to Use It
Pair this with warm wood tones or polished brass to prevent the room from feeling flat or cold. Use it in rooms where you want to highlight architectural features, as the darkness forces the eye to focus on the textures and objects placed against it.
The Mood
Living with a wall this dark feels grounded and restful rather than energizing. It creates a 'cocoon' effect that helps you disconnect from the busyness of the rest of the house, making it excellent for relaxation.
Colour harmonies
Complementary
Opposite on the colour wheel — bold, high-contrast pairings. Use for a feature wall or furniture you want to command attention.
Analogous
Neighbouring hues — cohesive and calm, great for layered schemes that feel collected rather than matched.
Split complementary
Near-opposites for strong contrast with a little less tension than a pure complement. A favourite of interior designers.
Triadic
Three evenly spaced hues — balanced, vibrant, and versatile. Keep one dominant and use the others sparingly.
Tetradic (square)
Four hues in a square on the wheel — rich, dynamic palettes. Best when one colour leads and the others accent.
Monochromatic
Dark, mid, and light steps on the same hue — a failsafe gradient for trim, walls, and accents without shifting colour family.
