Sea Life

Benjamin Moore · 2118-40

The Analysis

Sea Life is a deep, muted blue-grey that anchors a room by absorbing excess light rather than reflecting it. Because of its low LRV of 20.4, it will make a space feel more intimate and enclosed rather than airy or expansive.

It works best as a bold accent wall or a dramatic choice for a small, enclosed space like a study or powder room. If used on all four walls, it creates a moody, monochromatic look that needs balanced lighting to avoid feeling too dark.

LRV 20

History & Origin

This is a contemporary choice that leans into modern, sophisticated design trends. It lacks the chalky or historic pigments found in traditional palettes, making it better suited for clean, current architectural lines.

How to Use It

Pair this colour with warm wood tones like walnut to soften the coolness of the grey-blue. It looks sharp with matte black hardware for a modern edge or unlacquered brass for a high-contrast, upscale appearance.

The Mood

This shade provides a calm, grounded atmosphere that feels professional and steady. It is a restful choice for spaces where you want to minimize visual noise and focus on relaxation.

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.
