 The Idea of color is thus like white light, which “perplexes” within itself the genetic elements and relations of all the colors, but which is actualized in the diverse colors and their respective spaces. (Like the word “problem,” Deleuze uses the word “perplexion” to signify, not a coefficient of doubt, hesitation, or astonishment, but the multiple and virtual state of Ideas. Indeed, Deleuze adopts a number of Neoplatonic notions to indicate the structure of Ideas, all of which are derived from the root word pli [fold]: perplication, complication, implication, explication, and replication.) Similarly, the Idea of sound could be conceived of as a white noise, just as there is also a white society or a white language, which contains in its virtuality all the phonemes and relations destined to be actualized in the diverse languages and in the remarkable parts of a same language.
