Sea Urchin 3

Dulux

The Analysis

Sea Urchin 3 is a mid-tone blue-green that absorbs more light than it reflects, given its LRV of 38.44. Because it isn't a bright white or light pastel, it will make a room feel more intimate and grounded rather than expanding the space.

It functions best as a sophisticated main wall colour or a statement backdrop in rooms where you want to create a calm focal point. It has enough depth to hold its own against furniture without overwhelming the architecture.

LRV 38

History & Origin

This is a modern, transitional shade that fits well with contemporary design rather than specific period aesthetics. It lacks the chalky, dusty finish of traditional heritage paints, offering a smoother, updated look.

How to Use It

It pairs beautifully with warm wood tones like walnut or oak to balance the coolness of the teal. For hardware, use matte black for a modern edge or unlacquered brass to add a touch of warmth.

The Mood

This shade provides a restful and stable atmosphere, making it ideal for areas where you want to wind down. It feels clean and professional without the clinical coldness often found in pure blue tones.

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.
