Prussian Blue

Benjamin Moore · CW-625

The Analysis

Prussian Blue is a deep, saturated shade that absorbs a significant amount of light due to its low Light Reflectance Value (LRV) of 9.47. It will make a room feel smaller and more enclosed, which is perfect for creating a cozy, high-contrast environment.

Because it is so dark, this shade works best as a bold accent or a dramatic choice for a dedicated space like a library or a bedroom. Using it on all four walls creates a seamless, moody environment that makes other decor elements stand out.

History & Origin

This is a classic 'Heritage' tone frequently found in traditional libraries and studies of the 18th and 19th centuries. It carries a sense of formality and depth that feels established rather than trendy.

How to Use It

Pair this blue with warm wood tones, like walnut or oak, to soften the coldness of the hue. For hardware, unlacquered brass offers a sharp, elegant contrast, while matte black hardware will lean into a modern, monochromatic look.

The Mood

This colour provides a grounded, steady atmosphere that feels restful rather than energizing. It is a sophisticated choice for rooms where you want to retreat or focus, as it avoids the clinical feel of lighter blues.

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.
