Psychedelic art is any
art or visual displays inspired by
psychedelic experiences and
hallucinations known to follow the ingestion of psychoactive drugs such as
LSD and
psilocybin. The word "psychedelic" (coined by British psychologist
Humphry Osmond) means "mind manifesting". By that definition, all artistic efforts to depict the inner world of the psyche may be considered "psychedelic". In common parlance "psychedelic art" refers above all to the art movement of the late
1960s counterculture. Psychedelic visual arts were a counterpart to
psychedelic rock music. Concert posters, album covers, lightshows, murals, comic books, underground newspapers and more reflected not only the kaleidoscopically swirling colour patterns of LSD hallucinations, but also revolutionary political, social and spiritual sentiments inspired by insights derived from these psychedelic states of consciousness.
