Historically, color therapy has been used for thousands of years. Hippocrates was said to have applied his medicine in rooms painted in soothing, treating patients with different colored salves and ointments. In ancient Egypt, China and India, people were dipped in colored pigment or bathed in light that was filtered through colored-glass windows.

Today’s color therapists may use a variety of techniques to release physical, emotional, mental and spiritual blockages, including applying colored gemstones to the problem areas, colored light sessions, color breathing, color aromatherapy, color journaling, color affirmations, color visualization and recommendations for a color-related diet.​​
