Blue is a 1993 British drama film directed by Derek Jarman. It is his final feature film, released four months before his death from AIDS-related complications. Such complications had already rendered him partially blind at the time of the film's release and was only able to see in shades of blue.

The film was his last testament as a film-maker and consists of a single shot of saturated blue colour - specifically International Klein Blue (RGB 0, 47, 167, CMYK 100, 72, 0, 35). This fills the screen, as background to a soundtrack where Jarman's and some of his long-time collaborators' narration describes his life and vision.
