From ‘Blue’ (1993), Derek Jarman’s swan song ""Blue, made in 1993 when Aids was rendering Jarman blind, was his shocking, exquisite swan song. It has no images at all: just a still, blue screen through which Jarman intones an elegy for all that has been lost, loved and fought for. “I am in a blue funk . . . flashes of blue in my eyes. Blue of my dreams, slow blue hours, delphinium days.” Lovely essay this by
Can't help but imagine that "Battleship Island" also inspired the setting for Wes Anderson's "Isle of Dogs"
My favorite of all meditations on blue is Maggie Nelson's collection of meditations/essays "Bluets."
