About Colourwise

Understand a colour, identify it from a code, find what goes with it, and explore its mood, history and meaning — backed by calculated colour science and clearly sourced guidance.

Colourwise combines a calculated colour-intelligence engine — parsing, conversions, WCAG contrast, perceptual distance, harmony and classification — with a curated catalogue of significant colours, and clearly-sourced editorial context about mood, culture, history and use.

We distinguish calculated facts (conversions, distance, contrast ratios — mathematically derived and always correct within their documented assumptions) from curated judgements (mood associations, pairing suggestions, cultural meanings — written carefully, but inherently subjective or context-dependent). See methodology for how each is produced.

Colourwise is part of the HEKNO family of trust-led knowledge products, and reuses architectural patterns proven on Namewise — provenance-tagged data, controlled indexation, and provider abstractions ready for future data sources — rebuilt from the ground up for colour, not adapted from name data.
