Shades, tints and tones
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
The structural colour every interface actually runs on
Neutral grays carry no emotional charge, which is precisely their value: they let content and brand colour do the signalling. Their temperature matters more than designers expect — a cool gray beside a warm brand colour reads as a mistake.
Neutrality, professionalism, and precision. Overuse reads as noncommittal or unfinished.
Payne's gray, mixed rather than mined, became the painter's shortcut for atmospheric shadow. Swiss modernism turned systematic gray scales into a design methodology.
Build a full gray ramp before choosing a brand colour. Match the gray's temperature to the brand hue and reserve the darkest steps for type rather than large fills.
Common industries: Enterprise, Architecture, Automotive, Consulting, Hardware. Pairs well with a single saturated accent, warm white for text surfaces, near-black for hierarchy.
