Sea Star

Benjamin Moore · 2123-30

The Analysis

Sea Star is a mid-toned, muted blue-green that absorbs more light than it reflects, given its LRV of 32.16. Because it isn't a bright or reflective shade, it will make a room feel cozy and grounded rather than airy or expansive.

It functions best as a main wall color in rooms where you want a sophisticated backdrop. It is subdued enough to serve as a neutral, meaning it won't overwhelm your furniture or artwork.

How to Use It

This shade excels in bedrooms or home offices and pairs exceptionally well with warm, medium-toned woods like walnut or oak. For hardware, choose matte black for a high-contrast modern look or unlacquered brass to highlight the color's green undertones.

The Mood

This is a highly restful and stabilizing color that doesn't demand attention. It creates a calm, quiet atmosphere that feels steady and composed, making it ideal for spaces where you want to decompress.

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.
