What is Color Therapy?
Color therapy, also called chromotherapy, is an alternative healing practice that uses colored light, colored cloth, gemstones, or visualization to influence the body's energy systems. Its central claim comes from the Ayurvedic and yogic traditions of India. Each of the seven chakras (energy centers) corresponds to a specific color, and working with that color is said to restore balance in the associated center. Mainstream medicine classifies color therapy as pseudoscience. Its therapeutic claims have not been supported by controlled clinical trials.
Color Therapy vs adjacent practices
Color therapy is often confused with clinical light therapy, the evidence-based treatment for seasonal affective disorder (SAD). They are not the same practice. Clinical light therapy uses broad-spectrum white light at a specific intensity. The color plays no role, and the mechanism is circadian, not energetic. Color therapy makes a different claim: that the wavelength itself carries healing information that acts on the body's subtle-energy system. It is also distinct from color psychology, a mainstream research field that studies how color affects mood and cognition. Color psychology makes no claims about energy centers or healing. Crystal healing and color therapy overlap in practice: colored gemstones are typically assigned to specific chakras. But crystal healing is a broader framework with its own lineage, and the two traditions are not identical.
The tradition's account
The use of colored light for healing appears across a range of ancient traditions. Egyptian healing temples are described in historical sources as using colored glass or stone to channel sunlight into treatment rooms, with different hues assigned to different conditions. Ancient India is the deeper root. Early Āyurveda texts associate sunlight and color with the body's vital processes. The chakra system, which first appears in these same texts, provides the map. The chakra-color correspondence that contemporary practitioners use is sequential: red for mūlādhāra (root center), orange for svādhiṣṭhāna (sacral), yellow for maṇipūra (solar plexus), green for anāhata (heart), blue for viśuddha (throat), indigo for ājñā (third eye), and violet for sahasrāra (crown). In this model, imbalance in a center can be addressed by restoring the associated color-frequency. The methods include colored light projected onto the body, visualizing the color during meditation, or working with gemstones associated with the relevant hue.
The nineteenth-century American physician Edwin Babbitt systematized a Western version of the practice in his 1878 work The Principles of Light and Color. The book became influential in New Thought and Theosophical circles and introduced a color-organ system: colored glass panels through which sunlight was channeled onto the patient. Babbitt's device is the prototype of the chromotherapy equipment sold today. The New Thought movement absorbed color-healing ideas broadly in the late nineteenth and early twentieth centuries, which is part of why color therapy now appears across diverse contexts including Reiki, Āyurveda, and New Age practice.
In the index
No item in the index is dedicated to color therapy as a standalone practice. The framework it rests on — the chakra-color correspondence — runs through the Śaiva yogic teaching of Sadhguru. His curriculum treats the seven chakras and their energetic qualities as the operative map of the Isha yoga system. *Inner Engineering: A Yogi's Guide to Joy* is the introductory text where this framework is explained for a general reader. The color associations appear there as part of a larger account of prana and the subtle body, not as color therapy per se. Practitioners who work specifically with color through visualization or gemstone work typically draw on the same chakra-color map, whether or not they trace it to an explicitly yogic lineage.
What it isn't
Color therapy does not have standing as an evidence-based medicine. The National Center for Complementary and Integrative Health classifies it as an unproven complementary approach, and no color-therapy protocol has passed peer-reviewed clinical trials for any disease. The practice is better understood as a contemplative and ritual technology: a structured way of directing attention through color-associated visualization, embedded in an energetic cosmology rather than a physiological one. The distance between color-supported meditation, such as imagining a green light at the heart center, and color therapy as a clinical claim is significant. The contemplative dimension carries a long tradition. The clinical claim does not carry the evidence. Whether these two dimensions can be cleanly separated is a question practitioners and critics disagree about.
