Color harmonies

Complementary

The hue directly opposite on the color wheel. Maximum contrast, ideal for a single accent against a dominant brand color.

Analogous

Neighbouring hues that share a temperature. The safest harmony for calm, cohesive interfaces.

Triadic

Three hues evenly spaced 120 degrees apart. Vibrant and balanced — use one as dominant and the other two sparingly.

Split Complementary

The complement split into two adjacent hues. Nearly the contrast of complementary with noticeably less tension.

Square (Tetradic)

Four hues at 90-degree intervals. A rich set for illustration, data visualisation, and category coding.

Rectangle (Tetradic)

Two complementary pairs offset by 60 degrees. Gives two warm and two cool options in one system.

Monochromatic

A single hue across five lightness levels. The foundation of most UI scales and the most accessible starting point.

Meaning, psychology and brand usage

Space, clarity, and the most underrated design decision

White is read as clean and honest, and it functions less as a colour than as breathing room. Slightly warm whites feel considered and reduce glare; pure #fff can feel clinical at full-screen scale.

Purity and simplicity in Western markets; mourning in much of East Asia, which matters for global product launches.

Lead white dominated painting for two millennia despite being poisonous, replaced by titanium white in the twentieth century — the same pigment that whitens paper, paint, and toothpaste today.

Choose the white deliberately. An off-white page surface with pure white cards creates hierarchy without a single border.

Common industries: Technology, Healthcare, Architecture, Skincare, Retail. Pairs well with near-black type, one saturated accent, soft gray borders.
