The Analysis
Cardboard is a deep, earthy neutral that leans into a grounded, cozy aesthetic. Because of its lower LRV of 21.66, it absorbs a significant amount of light, which will make a large room feel more contained and intimate rather than spacious and airy.
This shade works best as a moody, sophisticated backdrop or a grounding accent wall. It provides a rich, tactile feel that makes furniture and artwork stand out against the wall rather than blending in.
LRV 22History & Origin
This is a classic 'earth-tone' shade that bridges the gap between traditional colonial palettes and modern, organic design. It feels rooted in history while remaining functional for contemporary homes.
How to Use It
It excels in studies, dens, or bedrooms where you want a sense of enclosure. Pair it with dark walnut wood tones and matte black hardware to emphasize the industrial or organic textures of the paint.
The Mood
Living with this color feels stable and grounded. It offers a restful, quiet energy that avoids the over-stimulation of brighter shades, making it an excellent choice for areas where you want to unwind.
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.
