The Analysis
John's Blue is a mid-toned slate blue that provides a steady, grounded presence in a room. With an LRV of 35.2, it absorbs a moderate amount of light, meaning it will create a cozy, enclosed feeling rather than making a small room look vast or airy.
This shade works best as a main wall colour in living spaces or bedrooms. It provides enough depth to act as a personality-driven backdrop without overwhelming the furniture or artwork in the room.
LRV 35History & Origin
This is a timeless, classic blue that leans toward a heritage aesthetic. It mirrors the traditional pigments used in historic homes but remains versatile enough to sit comfortably in a contemporary renovation.
How to Use It
Pair this blue with light oak wood tones for warmth or matte black fixtures to lean into a structured, modern look. It is an excellent choice for bedrooms or studies where you want a calm atmosphere.
The Mood
Living with this colour feels restful and composed. It lacks the over-stimulation of brighter pigments, making it a reliable choice for areas where you want to switch off and 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.
