Sash Blue

Dulux

The Analysis

Sash Blue is a mid-tone, desaturated blue that excels at making a room feel open and airy. With an LRV of 61.04, it reflects a significant amount of light, which helps smaller rooms feel larger and prevents the space from feeling cramped.

It works best as a primary wall colour because it is neutral enough to act as a backdrop while still providing clear colour. It creates a seamless transition between rooms and provides a clean, professional finish.

How to Use It

This shade suits bedrooms, bathrooms, and sun-drenched living areas perfectly. Pair it with light oak wood tones for a balanced look, or use matte black hardware to provide a sharp, modern contrast.

The Mood

This shade promotes a sense of calm and mental clarity without feeling cold. Because it leans towards a soft grey-blue, it is easy to live with daily and creates a restful environment for bedrooms or home offices.

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.
