Color harmonies
The hue directly opposite on the color wheel. Maximum contrast, ideal for a single accent against a dominant brand color.
Neighbouring hues that share a temperature. The safest harmony for calm, cohesive interfaces.
Three hues evenly spaced 120 degrees apart. Vibrant and balanced — use one as dominant and the other two sparingly.
The complement split into two adjacent hues. Nearly the contrast of complementary with noticeably less tension.
Four hues at 90-degree intervals. A rich set for illustration, data visualisation, and category coding.
Two complementary pairs offset by 60 degrees. Gives two warm and two cool options in one system.

Meaning, psychology and brand usage
Clean, technical, and effortlessly modern
Cyan and teal sit between blue's trust and green's calm, reading as clinical and precise. They perform well in data visualisation because they remain distinguishable for most forms of colour vision deficiency.
Water, hygiene, and clarity almost universally. Teal specifically carries a mid-century and medical association in Western design history.
Cyan entered common vocabulary through four-colour printing, where it is one of the process inks. Egyptian blue and later cerulean gave artists the closest historical equivalents.
Excellent for healthcare, SaaS, and fintech seeking approachability without blue's ubiquity. Deepen it for text use — bright cyan rarely reaches AA on white.
Common industries: Healthcare, SaaS, Travel, Water & utilities, Beauty. Pairs well with coral for warmth, deep navy for hierarchy, soft gray for restraint.
