Colour is largely assumed to be already in the world, a natural universal that everyone, everywhere understands. Yet cognitive scientists routinely tell us that colour is an illusion, and a private one for each of us; neither social nor material, it is held to be a product of individual brains and eyes rather than an aspect of things. This collection seeks to challenge these assumptions and examine their far-reaching consequences, arguing that colour is about practical involvement in the world, not a finalized set of theories, and getting to know colour is relative to the situation one is in – both ecologically and environmentally. Specialists from the fields of anthropology, psychology, cinematography, art history and linguistics explore the depths of colour in relation to light and movement, memory and landscape, language and narrative, in case studies with an emphasis on Australian First Peoples, but ranging as far afield as Russia and First Nations in British Columbia. What becomes apparent, is not only the complex but important role of colours in socializing the world; but also that the concept of colour only exists in some times and cultures. It should not be forgotten that the Munsell Chart, with its construction of colours as mathematical coordinates of hues, value and chroma, is not an abstraction of universals, as often claimed, but is itself a cultural artefact.

Canadian artist Michael Snow (born 1929) has been a central figure in North American postwar art; his influential films, such as Wavelength, rank alongside those of avant-garde auteurs such as Stan Brakhage and Gregory Markopoulos. Sequences is a complete monograph of this contemporary Renaissance man, who characterizes his oeuvre thus: my paintings are done by a filmmaker, sculpture by a musician, films by a painter, music by a filmmaker, paintings by a sculptor, sculpture by a filmmaker, films by a musician, music by a sculptor. Accordingly, Snow's texts acknowledge the difficulties an artist faces in approaching multiple disciplines. Across 17 chapters, the artist offers a complete overview of his own work--an editorial task with which he is intimately familiar after having produced several remarkable artists' books. At almost 400 pages, this hardcover is a tour- de-force on and by one of the most outstanding artists of our time.
