Color therapy: what it is and what is known

Color therapy, also called chromotherapy or colour therapy, uses colored light or colors to try to influence mood and health. People usually try it to relax or to ease stress, anxiety or sleep trouble. There is no reliable evidence that it helps beyond a placebo effect, though a calm, colorful setting can still feel pleasant.

What it is

Using color for well-being is very old. Color was used in ancient Egypt, China and Greece to evoke emotions, support spiritual practice and treat illness. In 1810, Goethe’s Theory of Colors linked colors with emotions. In the first half of the 20th century, Dinshah Ghadiali developed a system that gave each color specific effects on the body. Later systems shone colored light onto acupuncture points.

Practitioners say each color of light has its own wavelength and “vibration” that affects the body. They often describe red as stimulating and green as calming, and some link colors with organs and meridians. Some also make claims about conditions such as high blood pressure, migraine or arthritis. Those claims have no reliable support.

Color therapy is easy to confuse with two other things. Bright light therapy uses a white light box and is an established option for seasonal affective disorder (SAD). Color psychology studies how colors affect mood and feelings. It is related to color therapy but is a separate field.

What a session is like

Some alternative health clinics offer color therapy, often using LED lights that bathe you in a chosen color. Other practitioners shine colored light onto acupuncture points. In one research trial, people sat for 20 minutes in a room draped in blue or pink, wore goggles of the same color, and breathed deeply and relaxed. That gives a sense of what a session can look like, though it is not a standard format.

Before you book, it is worth asking:

• What training the practitioner has
• What they expect a session to change, and how many sessions they suggest
• What it costs
• Whether it fits alongside any care you already have

What research says

The research base is very thin. A 2018 review of Cochrane evidence on integrative practices found no Cochrane review of chromotherapy at all. Supportive accounts, such as a 1999 overview in the American Journal of Acupuncture, rely mainly on case studies.

A small 2022 randomized trial in a dental clinic found that adults who sat in a blue or pink room before root canal treatment had lower dental anxiety than those who waited in the waiting room. Blue and pink did not differ from each other. The groups also differed in setting, not just color, so the result may reflect a quiet room and time to relax. The authors called for larger studies. They also noted that the effects of light in general are often applied to specific colors without clear confirmation.

Color and mood are linked in everyday life. People across many cultures connect colors with emotions, and red tends to be the most arousing color and blue the least. Blue light from evening screens can lower melatonin and disrupt sleep. That is color psychology and light biology, not evidence that colored light treats illness. Bright white light boxes for SAD are a different case, and Mayo Clinic describes them as effective.

Who should be careful

The research reviewed for this page reports no specific side effects from colored light sessions. The bigger risk is relying on color therapy instead of seeing a clinician for anxiety, depression, sleep problems or high blood pressure. If you want light for low mood in winter, talk to a health care provider about bright light therapy. This matters especially if you have bipolar disorder or an eye condition such as glaucoma, cataracts or diabetic eye damage. Avoid lamps made for skin conditions, which mainly give off ultraviolet light. Keep bright or blue light out of your late evenings.

If you have symptoms that are new, severe or not improving, see a doctor or other licensed clinician rather than relying on color therapy alone.

How it fits with the pillars

For the mind, the reasonable core of color therapy is simple. Colors and calm settings can shift how you feel, and resting in a soothing room is a real experience. That is different from treating illness, and the evidence does not show it does that.

For the spirit, many people use color in meditation and spiritual practice. Chakra traditions link particular colors with energy centers in the body; that is a spiritual framework rather than a tested physical mechanism. If that side interests you, our guide to chakras and color explores it further.
