Did you know that adult coloring books have roots in the early 20th century? It all started with Swiss psychiatrist Carl Jung, who explored how colors affect our minds. He introduced the concept of color therapy, helping his patients express their emotions through colors and images. Jung believed that coloring could help people achieve a sense of balance and tranquility.

While these days color psychology is mostly used in fields like marketing and advertising, adult coloring books have become a favorite way for people to relax and get creative.
