Aquastone

Sherwin-Williams · SW9043

The Analysis

Aquastone is a mid-toned teal that acts as a bridge between blue and green. With an LRV of 49.13, it reflects a moderate amount of light, meaning it adds color without making a room feel dark or cave-like.

It works best as a primary wall color in spaces where you want personality without going too dark. It provides enough saturation to act as a backdrop, but it isn't so aggressive that it dominates a room.

History & Origin

This shade leans modern and fresh, moving away from the heavy, traditional palettes of the past. It feels like a contemporary evolution of the classic 'spa' blue-green aesthetic.

How to Use It

It pairs exceptionally well with warm wood tones like walnut or oak to balance out the cool undertones. For hardware, use matte black for a modern edge or unlacquered brass for a more refined, warm contrast.

The Mood

This color provides a balanced, restful environment that feels clean and composed. It is neither overly stimulating nor depressing, making it a reliable choice for areas where you want to maintain focus while staying relaxed.

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.
