It is a practice linked to the wellness and health sector in which the presence of colours is exploited in various ways. The schools of chromotherapy are inspired by different concepts more or less in contrast with each other, but all relate the state of well-being with the presence of one or more colors, in various combinations. We find chromotherapies based on vibrational concepts, linked to transcendental, mystical and holistic practices, up to chromotherapy that takes its cue from psychotherapeutic concepts and the ability of certain colors to be associated with certain conditions and to arouse certain memories. The use of chromotherapy as an aid is well established, and many areas provide environments with colors that can predispose to certain emotional reactions. The use as a cure tout court for everything, however, seems quite groundless.
