Reef Blue

Behr · S490-3

The Analysis

Reef Blue acts as a mid-tone balance, sitting right in the middle of the light spectrum with an LRV of 47.1. It provides enough saturation to define a space without making a room feel boxed in or claustrophobic.

This is a versatile shade that works best as a primary wall color for a bold statement or as a cabinet color in a kitchen. Because it isn't overly dark, it serves as a reliable backdrop that doesn't compete with your furniture.

How to Use It

Pair this with light oak wood tones to soften the blue, or use matte black hardware to lean into a modern look. It performs exceptionally well in bathrooms or bedrooms where you want a cool, composed atmosphere.

The Mood

Living with this shade feels calm and grounded rather than jarring or high-energy. It is a stable, consistent color that brings a sense of order and cleanliness to busy areas like kitchens or bathrooms.

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.
