Gulf Stream

Behr · 570B-5

The Analysis

Gulf Stream is a mid-tone blue with a noticeable cool grey undertone. With an LRV of 31.97, it absorbs a fair amount of light, which creates a cozy, enclosed feeling rather than making a small room feel larger or airier.

It works best as a bold, saturated accent wall or for built-in cabinetry where you want to create a focal point. Using it on every wall in a room can feel quite heavy, so it is often better paired with crisp, bright white trim to keep the space from looking dingy.

LRV 32

History & Origin

This is a contemporary choice that leans toward modern interior design. It lacks the chalky, muted qualities of traditional historical palettes, making it feel fresh and relevant for today's homes.

How to Use It

It pairs beautifully with warm wood tones like walnut or teak, which cut through the blue’s coolness. Use matte black hardware for a high-contrast, modern look, or brushed brass if you want to soften the edges of the room.

The Mood

This color feels balanced and stable, making it a solid choice for rooms where you want to focus or unwind. It avoids being too 'nursery blue' or hyper-energizing, providing a grounded, professional atmosphere.

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.
