The audio poetically explores the literal and allegorical experience Jarman had as he struggled with AIDS, the battle he ultimately lost. It also includes an exploration of blue as a color and as a symbol with a multitude of meanings. As the viewer stares into the blue screen, they are given a space to meditate on the words spoken by the narrators of the film, and an immersing environment in which they can reflect on their own lives.
The narration in the movie Blue ends with the lines "In time, no one will remember our work. Our life will pass like the traces of a cloud and be scattered like mist that is chased by the rays for the sun for our time is the passing of a shadow. I place a delphinium, Blue, upon your grave."
The most famous contributor to the audio was the British actor Tilda Swinton. The music for the audio was composed by various artists, including Simon Fisher Turner, John Balance, Momus, Peter Christopherson, and Karol Szymanowski.
Upon its initial television release, the British Television Network Channel 4 and BBC Radio 3 released a simultaneous broadcast of the audio track with Channel 4 including the blue screen visual in addition to the audio. To date, the film has been released on DVD in Britain, Germany, and Italy.
