Royal Regatta 3

Dulux

The Analysis

Royal Regatta 3 is a deep, saturated blue that absorbs a significant amount of light due to its low Light Reflectance Value (LRV) of 16.38. Because it reflects so little light, it will make a room feel more intimate and enclosed rather than airy or expansive.

This is a bold choice best used as a feature wall, in a dedicated media room, or for cabinetry. Using it on every wall in a small room can feel overwhelming unless you are deliberately aiming for a 'moody' or 'cocooning' effect.

History & Origin

While deep blues are a staple of traditional interiors, this particular shade feels contemporary and sharp. It avoids the dusty, grey undertones found in Victorian heritage palettes, giving it a fresh, modern edge.

How to Use It

Pair this with warm walnut wood tones or brushed brass hardware to prevent the room from feeling too cold. It works exceptionally well in bedrooms or studies; keep your ceilings and trim crisp white to provide a necessary visual break from the dark walls.

The Mood

Living with this shade feels grounded and stable. It is a restful, cooling colour that reduces visual clutter, making it excellent for rooms where you want to signal to your brain that it is time to wind down.

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.
