Apollo Blue

Benjamin Moore · CW-645

The Analysis

Apollo Blue is a deep, muted teal-gray that absorbs a fair amount of light, making it feel grounded and cozy rather than bright. Because of its low Light Reflectance Value (LRV) of 21.99, it will visually push the walls inward, creating a more intimate, enclosed atmosphere in large spaces.

This colour works best as a moody backdrop or a high-impact accent wall. It is too heavy for a whole-house palette, but it excels at defining specific zones like a home office or a feature wall in a primary bedroom.

History & Origin

Apollo Blue carries a modern, transitional aesthetic. It lacks the vintage feel of traditional period colors, fitting much better into contemporary or curated designer homes.

How to Use It

Pair this with warm walnut wood tones to prevent the room from feeling too cold, or use matte black hardware for a sharp, modern contrast. It performs best in rooms with plenty of task lighting, as the darker pigment can make corners feel dim without proper illumination.

The Mood

Living with this shade feels calm, steady, and deliberate. It lacks the jittery intensity of brighter blues, making it a highly restful choice for spaces where you want to signal to your brain that it is time to unwind.

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.
