Sea Urchin 2

Dulux

The Analysis

Sea Urchin 2 is a muted, desaturated teal that acts as a calming anchor for a room. With an LRV of 26.16, it is a mid-tone shade that absorbs more light than it reflects, meaning it will make a space feel cozy and contained rather than bright and expansive.

This is an excellent choice for a secondary wall colour or a statement piece in a study or bedroom. Because of its medium depth, it works best as a primary wall colour in smaller, intimate rooms where you want to embrace a sense of shelter.

LRV 26

History & Origin

This shade leans toward a modern, sophisticated aesthetic. It feels contemporary and curated, lacking the traditional heavy saturation of historical Victorian or Georgian dark tones.

How to Use It

Pair this with warm walnut wood tones to balance its cool undertones or use matte black hardware for a sharp, modern contrast. It performs best in rooms with plenty of natural light, as the daylight prevents the grey undertones from feeling muddy.

The Mood

Living with this colour feels grounding and stable. It avoids the clinical sterility of bright whites, offering a restful, quiet backdrop that stays visually interesting without being over-stimulating.

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.
