Dark Harbor

Benjamin Moore · CSP-720

The Analysis

Dark Harbor is a deep, moody teal that absorbs a significant amount of light due to its low LRV of 5.49. Because it pulls light into the walls rather than reflecting it back, it will make a room feel smaller, more intimate, and grounded.

This shade works best as a bold accent, such as on cabinetry, library shelving, or a single statement wall. Using it on every surface in a small, windowless room can feel overwhelming unless you are specifically aiming for a dramatic, immersive effect.

LRV 5

History & Origin

It leans into a modern interpretation of heritage design, often found in moody, updated Victorian studies or gentleman’s lounge aesthetics. It feels intentional and refined rather than historically rigid.

How to Use It

Pair this with warm wood tones like walnut or teak to soften the cool teal undertones. For hardware and fixtures, unlacquered brass or brushed gold provides a high-contrast pop, while matte black keeps the look sleek and modern.

The Mood

This color provides a restful, cocooning environment that feels sophisticated and calm. It isn't energizing; instead, it is best suited for rooms where you want to retreat or relax.

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.
