CHROMA

Every colour,
one solid.

The Institute of Colour Science keeps the reference model: four thousand samples of everything your screen can say, suspended in a cylinder of hue, chroma and lightness.

Hue

The angle. Walk the rim of the cylinder and you pass every family: red into orange into the long green noon, home through violet.

The named collection

Colours with
criminal records.

Most colours live and die as coordinates. A few earned names, patents, lawsuits, and graves. Six from the Institute's vault:

#002FA7

International Klein Blue

PATENTED 1960 · PARIS

Yves Klein bound ultramarine in a resin that refuses to dull it, then patented the recipe. The only colour with an artist's signature.

#8F00FF

Mauveine

SYNTHESISED 1856 · LONDON

William Perkin, 18, failed to make quinine and accidentally invented the first synthetic dye. Fashion forgave the failure instantly.

#4A3B2A

Mummy Brown

DISCONTINUED 1964 · RAN OUT

Ground from actual Egyptian mummies until the supply — mercifully — was exhausted. Pre-Raphaelites buried their last tube in the garden.

REFLECTS 0.035%

Vantablack

LICENSED 2016 · EXCLUSIVELY

A forest of carbon nanotubes that eats light whole. Licensed to a single sculptor, to the loud fury of every other one.

#39FF88

Paris Green

BANNED · ARSENIC

The most beautiful pigment of the 19th century, and its most patient murderer. Wallpaper, dresses, and then the obituaries.

#FF7527

Safety Orange

STANDARDISED 1955 · ANSI

Chosen by committee to disagree with every landscape on Earth. The only colour whose job is to be seen and never loved.
