The Analysis
Pen Friend is a deep, saturated navy that absorbs significant light due to its very low LRV of 6.44. It will make a room feel enclosed and intimate rather than spacious, effectively 'pulling in' the walls to create a cozy, dramatic atmosphere.
This is a bold, high-impact choice best used as a statement wall or for full-room color drenching to create a moody aesthetic. It is too dark to serve as a neutral backdrop for most standard living spaces.
LRV 6History & Origin
Deep blues like this are a staple of modern interior design, though they echo the traditional library or study aesthetic found in heritage homes. It feels current and sophisticated rather than dated.
How to Use It
Use this in smaller rooms like powder rooms, studies, or media rooms where you want drama. Pair it with warm brass hardware to pop against the blue or matte black for a seamless, monochromatic look; avoid pale woods which may look starkly out of place.
The Mood
Living with a shade this dark feels grounding and stable. It provides a restful, low-stimulation environment that is excellent for areas where you want to signal to your brain that it is time to relax or focus.
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.
