Unique colour list

This is a curated list of single-word named colours with fixed hex values and approximate dates of first recorded use.

The list is intentionally limited, historically grounded, and opinionated.

List of colours

Rules and constraints

One name, one colour
Each colour name maps to a single, fixed hex value. Names are not reused, aliased, or shared across multiple colours.
One colour, one name
No two entries represent the same or perceptually identical colour. Near-duplicates are intentionally excluded, even if historically attested.
Distinct by perception, not maths
Colours must be visually distinguishable to a typical viewer under normal conditions. Numeric separation alone is insufficient justification for inclusion.
Names must be established or defensible
Colour names are drawn from historical usage, material pigments, cultural convention, or long-standing descriptive practice. Coined names are avoided unless necessary to preserve clarity or distinctness.
Historical metadata is descriptive, not authoritative
Recorded years indicate earliest known usage as a colour term. They do not imply invention, exclusivity, or universal adoption.
No dependency on web colour standards
The list does not conform to, derive from, or attempt compatibility with CSS colour keywords, system palettes, or accessibility-driven contrast schemes.
Digital representation is a compromise
Hex values are practical approximations. They represent intent, not a claim of absolute accuracy across devices, colour spaces, or lighting conditions.
Categories are organisational, not normative
Family groupings and sort orders exist to aid navigation. They do not imply hierarchy, primacy, or correctness.
The list is finite by design
This is a curated reference, not an exhaustive catalogue. Absence is intentional and should not be read as oversight.
