In 1986, Derek Jarman, one of the most prominent British film directors, author of Jubilee, Caravaggio or Edward II, finds out that he is HIV-positive. Due to complications, he begins to lose his sight, but does not give up his work.
He creates an avant-garde film Blue (the screen filled entirely with blue, which is the last colour recognized by the artist) and writes an essay Chroma. A Book of Colour. It is a poetic record of the dying process, but also a political theory and history of colours.
