For example, Indian yellow, a mysterious pigment now lost, was probably produced from the boiled urine of ill-nourished cows fed on a diet of mango leaves and cochineal, a crimson-like dye, is produced by crushing the tiny insect Dactylopius coccus – 70,000 for one pound of colourant. The most commonly touched-upon area is, unsurprisingly, the history of art, since many of the colours discussed are pigments. This really is an effective structural conceit and St Clair is able to dance effortlessly through an astonishing range of subjects. She finds colourful threads running through the tapestry of history, gives them a tug, and follows them into interesting and unexpected realms. St Clair takes 75 shades, hues, pigments and dyes, and gives us a few punchy pages on each. Suitably sensitised to the intriguing and mysterious world of colour, we’re ready for the main event. We’re also introduced to surrounding metaphysical debates, doomed attempts to catalogue colours, and the troublesome zone where language and colour perception overlap.

In introductory sections, Kassia St Clair gives us a solid grounding in the science of colour for those of us who’ve wondered why mixing light of different colours produces white, while mixing paint of different colours produces a dark sludgy mess. The secret lives of colour does not disappoint – a vivid exploration of the world of colour and our colourful world.

Colour isn’t often confronted as a subject in its own right, but when it is, the results tend to be fascinating.
