Only those who love colour are admitted to its beauty and immanent presence. It affords utility to all, but unveils its deeper mysteries only to its devotees. Johannes Itten On Colour... draws on the theories of colour harmony that Johannes Itten taught at the Bauhaus, and on the literature of Mazdaznan, Rosicrucianism and Theosophy. It describes how one can, potentially, produce the white cloud of invisibility and documents the author’s own attempts to manifest the cloud. These manifestations have a complex group of antecedents that include Lawrence Weiner’s early spray-painted works, John Latham’s One Second Drawings, Robert Irwin’s luminous disc paintings of the 1960s and representations of the ineffable made by spiritualists and occultists.
