One of the first psychologists who in the early twentieth century used the coloring mandalas as a relaxation technique was Carl Gustav Jung. He prescribed his patients coloring mandalas as part of the therapy.

Coloring appeared in the United States as part of the "democratization of art", inspired by a series of lectures by British artist Joshua Reynolds and the works of the Swiss educator Johann Heinrich Pestalozzi together with his student Friedrich Friedrick Frobel.
