Inspired by a sentence by Reinhold Messner describing his expeditions as vast invisible works of art, the Italian artist Alice Guareschi set out on an adventure through three continents, travelling according to a code: colour. From the White Sea in north-western Russia to the Yellow Sea in north-eastern China, the Red Sea in eastern Eritrea and the Black Sea in northern Turkey, she filmed with a small video camera and turned what she found and what struck her into a 92-minute road movie. The book takes the reader along the same journey through a selection of stills from the film, notes by the artist and a collection of postcards sent from abroad.
