Quick Answer
Color therapy (chromotherapy) uses specific wavelengths of light to support physical and energetic health. The seven chakra colours range from red (root) through orange, yellow, green, blue, indigo, to violet (crown), each corresponding to a specific frequency and function. Dinshah Ghadiali's Spectro-Chrome system (1920s) and Theo Gimbel's Hygeia colour therapy provide the most developed Western frameworks for practical colour healing.

What Is Color Therapy? History and Overview
Color therapy, also called chromotherapy or light therapy, uses specific wavelengths of visible light to influence physical, emotional, and energetic states. The underlying premise is that different colours of light carry different frequencies, and that these frequencies interact with the human body's own electromagnetic fields, cellular chemistry, and energetic systems in specific and therapeutically useful ways.
The use of colour for healing is ancient. The ancient Egyptians built healing rooms with coloured glass panels through which sunlight entered to produce coloured light baths for patients. Ancient Greek physicians including Pythagoras and later Avicenna described specific therapeutic uses of colour. In Ayurvedic medicine, colour has been used therapeutically for thousands of years within the framework of the three doshas and their elemental correspondences.
In Western medicine, the systematic use of light and colour for therapeutic purposes gained serious scientific attention in the late nineteenth century. Niels Finsen won the Nobel Prize in Medicine in 1903 for his demonstration that ultraviolet and visible light could treat certain skin conditions including lupus vulgaris. This opened a period of intensive research into phototherapy that continued through the early twentieth century until the development of antibiotics shifted medical attention away from non-pharmaceutical treatments.
The modern revival of colour therapy draws on three primary streams: the Spectro-Chrome system developed by Dinshah Ghadiali in the 1920s-1930s; the spiritual colour science developed by Johann Wolfgang von Goethe and extended by Rudolf Steiner; and the clinical phototherapy research that has expanded dramatically since the 1990s with the development of LED technology enabling precise, controllable light delivery at specific wavelengths.
The Seven Chakra Colours: Frequencies and Functions
The chakra system, originating in ancient Indian yogic tradition and described in texts including the Yoga Sutras of Patanjali and the Shiva Samhita (ca. 1500 CE), maps seven primary energy centres along the spinal axis, each associated with specific physical, psychological, and spiritual functions. The correspondence between these seven centres and the seven colours of the visible spectrum (the rainbow order) is one of the most widely used frameworks in contemporary colour healing.
The Root Chakra (Muladhara) at the base of the spine corresponds to red, the longest visible wavelength (620-750 nm) and the lowest vibrational frequency of visible light. Red's grounding, activating, and stimulating qualities align with the root chakra's function: governing physical survival, earthly connection, the basic security of physical embodiment, and the healthy assertion of life force. Root chakra imbalances - feeling ungrounded, unsafe, disconnected from the body or physical reality - respond in colour therapy practice to red and earth tones.
The Sacral Chakra (Svadhisthana) in the lower abdomen corresponds to orange, the second visible wavelength (590-620 nm). Orange combines red's vitality with yellow's creativity, aligning with the sacral chakra's functions of sexuality, creative expression, emotional flow, and pleasure. Orange in colour therapy is used to support creative blocks, emotional suppression, and difficulties with boundaries and desire.
The Solar Plexus Chakra (Manipura) at the upper abdomen corresponds to yellow (570-590 nm), associated with intellectual activity, personal power, will, and self-definition. The solar plexus is the centre of personal identity and the capacity for self-directed action. Yellow in colour therapy supports mental clarity, personal boundaries, and the healthy assertion of individuality.
The Heart Chakra (Anahata) at the centre of the chest corresponds to green (495-570 nm), the middle wavelength that balances warm and cool colours. Green is associated with harmony, balance, compassion, and the healing principle itself. The heart is the integrating centre of the chakra system, the bridge between the lower three (physical) and upper three (spiritual) chakras. Green supports emotional balance, compassion, and the capacity for loving connection.
The Throat Chakra (Vishuddha) at the throat corresponds to blue (450-495 nm), associated with communication, truthful expression, and the creative power of sound and language. Blue in colour therapy has calming, cooling, and anti-inflammatory effects in both clinical research and traditional use, consistent with the throat chakra's function as a centre of calm, clear expression.
The Third Eye Chakra (Ajna) at the forehead between the eyebrows corresponds to indigo (420-450 nm), a deep blue-violet associated with intuition, inner vision, and the perception of subtle realities. Indigo supports contemplative depth, inner knowing, and the faculty of imagination.
The Crown Chakra (Sahasrara) at the top of the head corresponds to violet (380-420 nm) or white (all wavelengths combined). Violet is the highest frequency of visible light, associated with spiritual consciousness, universal connection, and the capacity for transcendence. Crown chakra work in colour therapy uses violet and white to support meditation, spiritual opening, and the integration of spiritual experience into daily life.
Dinshah Ghadiali and the Spectro-Chrome System
Dinshah Pestonji Framji Ghadiali (1873-1966) was a Parsee-born American inventor and colour healer who developed what he called the Spectro-Chrome system of chromotherapy in the 1920s and 1930s. Born in India, he studied medicine and engineering before emigrating to the United States in 1911, where he developed his comprehensive system of colour healing based on the relationship between the body's chemical elements and specific light wavelengths.
Ghadiali's fundamental hypothesis was that the body's organs and functions require specific mineral elements to operate optimally, and that these elements' electromagnetic characteristics correspond to specific colour wavelengths. Deficiency of an element in the body creates a corresponding deficiency in the body's electromagnetic spectrum, and restoring that wavelength through coloured light exposure replenishes the element's influence on the body's chemistry. This theory, while not accepted by mainstream biochemistry, provided a coherent framework for his clinical practice.
His Spectro-Chrome Metry Encyclopaedia (1933), published in three volumes, provides extraordinarily detailed protocols: specific colours for hundreds of conditions, applied to specific body areas (tonation areas) for specific durations and at specific times of day. The system uses five primary colours (red, yellow, green, blue, and violet) and seven additional intermediary colours to address the full spectrum of human health conditions.
Ghadiali attracted significant attention from the medical establishment, not all of it hostile. The American Medical Association pursued and prosecuted him, and he spent periods in legal difficulties throughout the 1930s-1950s. However, his system continued to be used by practitioners throughout this period and his work was continued by his son Darius after his death. Today his grandson Jay Dinshah and others continue his work through the Dinshah Health Society.
"Colour is the medicine of the future."
- Dinshah Ghadiali, Spectro-Chrome Metry Encyclopaedia (1933)
Theo Gimbel and the Hygeia Colour Therapy System
Theo Gimbel (1920-2006) was a German-born British colour healer who represents the most sophisticated synthesis of spiritual philosophy and practical colour therapy in the Western tradition. A student of Rudolf Steiner's Anthroposophy, Gimbel founded the Hygeia Studios and College of Colour Therapy in Tetbury, Gloucestershire, UK, which trained practitioners in his integrated approach until his death.
Gimbel's approach drew from three primary sources: Goethe's phenomenological colour theory, Steiner's spiritual elaboration of Goethean colour science, and Dinshah's practical clinical protocols. Where Dinshah focused primarily on physical conditions, Gimbel extended colour therapy to the psychological, emotional, and spiritual dimensions of human experience, developing what he called a "colour therapy of the whole person."
His books Form, Sound, Colour and Healing (1987) and Healing with Colour and Light (1994) remain foundational texts in British colour therapy training. Gimbel's Hygeia system uses a specific set of coloured silks, colour cards, and coloured light sources, combined with a detailed assessment process that considers the client's colour preferences and aversions as diagnostic information about their current energetic state.
Gimbel specifically developed work with the colour complementaries (complementary colour pairs: red-green, orange-blue, yellow-violet) as a therapeutic tool. A strong preference for one colour combined with aversion to its complementary often reveals a compensatory pattern in the person's energetic system. Working therapeutically with the avoided colour helps restore balance. This approach reflects both Steiner's insight that colours work in polar relationships and Goethe's discovery that each colour calls for its complementary in the eye after extended exposure (afterimage).
Goethe's Colour Theory and Steiner's Spiritual Colour Science
Johann Wolfgang von Goethe's Theory of Colours (Farbenlehre, 1810) was not primarily intended as a scientific alternative to Newton's optics (though Goethe did dispute Newton's analysis). It was a phenomenological study of colour as a qualitative experience, describing the psychological and spiritual qualities of colours in terms of their relationship to light and darkness.
Goethe described colour as arising from the interaction of light and darkness rather than as simply being components of white light (Newton's view). The warmest colours (red, orange, yellow) arise toward the light side; the coolest (blue, indigo, violet) arise toward the dark side; green appears in the middle. This polarity of warm and cool colours carries psychological significance: warm colours advance toward the viewer and stimulate; cool colours recede and calm. Goethe's precise descriptions of each colour's psychological quality remain remarkably consistent with contemporary chromotherapy experience.
Rudolf Steiner extended Goethe's colour phenomenology into a full spiritual science of colour in his lectures published as Colour (GA 291, various lecture dates 1921-1924). Steiner describes colour as literally the soul of the visible world: "Colour is the soul of nature and of the cosmos, and we participate in this soul when we experience colour." His specific descriptions of each colour's spiritual quality provide rich depth for therapeutic colour work:
"Colour is the soul of nature and of the cosmos, and we participate in this soul when we experience colour."
- Rudolf Steiner, Colour (GA 291)
Steiner describes red as the "living" colour that expresses the being's own life force outward; blue as the "devotional" colour that draws consciousness inward toward the divine; yellow as the "radiant" colour of active spiritual light; green as the "dead image of life," the colour of physical nature in its achieved form; and white and black as the extremes that are not colours in the full sense but the poles between which colour occurs.
This Goethean-Steinerian framework transforms colour therapy from a mechanical wavelength application into a living dialogue between the practitioner's consciousness, the colour's quality, and the client's energetic reality. It is the philosophical foundation that Theo Gimbel's Hygeia system builds on and that distinguishes it from more technically-oriented chromotherapy approaches.
The Science of Light: What Research Shows
The scientific validation of colour and light therapy has expanded significantly since the development of precise LED technology in the 1990s. While the spiritual and energetic dimensions of colour therapy are not directly measurable by current instruments, several physical light therapy applications have accumulated substantial clinical evidence.
Red light photobiomodulation (also called low-level laser therapy or LLLT) uses red and near-infrared light (620-1000 nm) to stimulate tissue healing, reduce inflammation, and manage pain. Multiple systematic reviews and meta-analyses have confirmed its efficacy for wound healing, musculoskeletal pain, and nerve regeneration. The FDA has cleared specific red light devices for some applications. The mechanism involves light absorption by cytochrome c oxidase in mitochondria, stimulating cellular energy production.
Blue light therapy at 450-490 nm is standard clinical treatment for neonatal jaundice (phototherapy), breaking down bilirubin in skin and blood. It is also effective for seasonal affective disorder (SAD) through its suppression of melatonin and regulation of circadian rhythms. Research consistently supports blue light for SAD treatment; it is recommended by clinical guidelines in multiple countries.
Research by Rami Burstein and colleagues at Harvard Medical School, published in Nature Neuroscience in 2016, found that green light (520 nm) reduced pain sensitivity in migraine patients by approximately 20% compared to other wavelengths. This finding, subsequently replicated in animal and human studies, suggests that specific visible wavelengths interact with pain processing pathways in ways that clinical chromotherapy proponents have long asserted.
The Dinshah Health Society notes that Ghadiali's original clinical observations, while not validated in controlled trials, were based on careful empirical observation over decades of clinical practice. The absence of controlled trials during his active period reflects the economic and regulatory context of early twentieth century medicine rather than inherent implausibility of his claims.
Red, Orange, and Yellow: Grounding and Activating Colours
The three warmer colours of the chakra spectrum correspond to the lower three chakras and share a quality of outward movement, stimulation, and earthly engagement. Colour therapy uses these colours to address deficiency in physical vitality, creative expression, and personal confidence.
Red is the most physically activating of the spectrum. Chromotherapy protocols use red light to stimulate circulation, address chronic fatigue, and support conditions involving insufficient physical vitality. Ghadiali used red in his Spectro-Chrome system for anaemia, fatigue, and conditions involving circulatory insufficiency. Modern photobiomodulation research in the red-near infrared range confirms significant effects on cellular energy production and tissue healing.
At the chakra level, red root chakra work is appropriate for people who feel disconnected from their bodies, who have difficulty feeling safe in the physical world, or who experience chronic anxiety related to survival and security. Wearing red, spending time in red-lit environments, or practising root chakra visualisation with red light all support these qualities.
Orange in colour therapy supports creative blocks, emotional suppression, and conditions involving stagnation of the vital energies. It combines red's physical activation with yellow's creative-mental quality. Gimbel recommends orange for people in states of emotional withdrawal, grief that has become chronic and stuck, or creative paralysis. Physically, he associates orange with the digestive and reproductive systems, consistent with the sacral chakra's anatomical correspondences.
Yellow stimulates mental activity, supports digestion, and addresses conditions of mental sluggishness or low self-confidence. Ghadiali used yellow in his Spectro-Chrome system for nervous system conditions, depression, and constipation. The solar plexus chakra's association with personal power and will means that yellow colour therapy is particularly relevant for people working through issues of personal authority, self-trust, and the capacity to act from inner conviction.
Green and Blue: Balancing and Calming Colours
Green occupies the centre of the visible spectrum, sitting between the warm and cool colours, and is associated in both chakra work and chromotherapy with the healing, balancing, and harmonising principle. Ghadiali used green as a universal harmoniser: where he was uncertain about a condition's specific requirements, green was the safe default choice because of its normalising and balancing rather than stimulating or suppressing quality.
The heart chakra's green corresponds to the qualities of compassion, equilibrium, and the capacity for loving presence without projection or neediness. Heart chakra colour work with green supports people moving through grief, people who have difficulty receiving love (as distinguished from giving it), and people working to develop genuine compassion rather than co-dependent emotional merging.
Research by Burstein and colleagues on green light's pain-reducing effects suggests a physical mechanism for some of the balancing and harmonising properties that colour therapy practitioners attribute to green. If green light genuinely reduces pain sensitivity through opioid pathways, it would provide a physical substrate for green's role as a "comfort" colour in both traditional and contemporary colour healing.
Blue is the cooling, calming colour of the spectrum, associated with the throat chakra, communication, and the reduction of excess heat and inflammation. In chromotherapy, blue is used for fever reduction, inflammatory conditions, and states of mental or emotional agitation. Ghadiali used blue for conditions involving excess heat: fevers, inflammatory skin conditions, nervous excitement. Modern clinical blue light therapy for SAD and sleep regulation is consistent with blue's traditional role as a regulating and calming influence on physiology.
Colour Breathing Meditation for Chakra Balancing
Sit comfortably with your spine erect. Close your eyes. Choose a chakra to work with and its corresponding colour. Begin breathing slowly and deeply. On each inhalation, visualise inhaling the chosen colour as a stream of coloured light entering through the nose, travelling down the spine, and gathering at the chakra's location. On each exhalation, visualise any tension, congestion, or darkness releasing from that area as a muddy brown or grey mist. Continue for 10-15 minutes. Observe the sensations, images, or feelings that arise during and after the practice.
Indigo and Violet: Upper Chakra Colours
The upper chakra colours, indigo and violet, are associated with the third eye and crown chakras respectively, and with the more subtle and spiritual dimensions of human experience. In chromotherapy, these high-frequency colours are used for conditions involving the nervous system, the perceptual and cognitive functions, and the spiritual dimension of health.
Indigo (the third eye colour) in Gimbel's system supports intuitive development, the capacity for inner vision, and the ability to perceive patterns and meanings beyond the surface of events. It is associated with the pituitary gland and the deep regulatory functions of the endocrine system. Ghadiali used indigo for conditions involving nervous system agitation, insomnia, and acute inflammatory pain, consistent with indigo's traditional role as a colour that brings depth and stillness to over-active mental states.
Violet, the crown chakra colour and the highest frequency of visible light, works at the level of the nervous system and spirit. In chromotherapy, violet is used for conditions involving the nervous system, for spiritual development work, and for situations requiring a cleansing and purifying influence. The medical use of ultraviolet (UV) light for skin conditions (psoriasis, eczema) in dermatological phototherapy demonstrates that light at the violet-ultraviolet end of the spectrum has measurable biological effects on skin and immune function.
White, sometimes associated with the crown chakra as the synthesis of all colours, is used in colour healing for conditions requiring deep purification and spiritual clarity. In Gimbel's system, white light baths (full-spectrum light exposure) serve as a general tonic and balancing influence, consistent with the well-documented benefits of natural sunlight exposure for mood, immune function, and circadian regulation.
Practical Color Therapy Methods for Home Use
Seven Accessible Home Colour Therapy Practices
- Colour breathing meditation: Described above. Practice daily with the colour corresponding to the chakra you want to support. Ten minutes produces noticeable effects within 2-3 weeks of consistent practice.
- Coloured light environment: Use coloured light bulbs or coloured gels over standard lamps. Spend 20-30 minutes daily in a room lit by the colour you are working with. Red and orange for morning activation; green and blue for afternoon balance; violet or deep blue for evening wind-down.
- Colour clothing: Consciously choose to wear the colour of the chakra you want to support. This is a subtle but consistent input throughout the day as your eyes continually register colour in peripheral vision.
- Solar-charged water: Fill a coloured glass bottle with water and place it in sunlight for 4-8 hours. The coloured glass filters sunlight to produce the corresponding wavelength in the water. This traditional preparation is used in Ayurveda and various colour healing traditions.
- Colour art therapy: Use the colour of the chakra you are working with as your primary medium for a drawing or painting session. Allow the hand to move freely rather than planning an image. What arises on the paper often reveals the quality of the energetic state you are working with.
- Coloured gemstones: Crystals and gemstones of the chakra colours can be placed on the corresponding body area during relaxation. The colour of the stone visually reinforces the colour association, and the stone's own crystalline properties add a complementary influence.
- Nature colour immersion: Spend time in natural environments saturated with the colour you are working with. Immersion in green spaces (parks, forests) for heart chakra work; time watching sunsets for root and sacral chakra colours; clear daytime sky for throat and third eye colours.
Colour therapy, at its most accessible, is simply the conscious use of what we encounter daily. Every moment in a natural or built environment involves colour input that influences mood, energy, and physical state, largely below conscious awareness. Bringing conscious intention to colour choices, in clothing, environment, and visualisation, transforms a constant background influence into a deliberate therapeutic practice.
For those who want to study colour therapy more formally, Theo Gimbel's books provide the most philosophically rich and practically grounded starting point. Peter Mandel's Colorpuncture system, which combines colour light delivery at specific acupuncture points with kirlian photography diagnostic assessment, represents a more technical approach that bridges chromotherapy and Traditional Chinese Medicine. Dinshah Ghadiali's encyclopaedia, now available through the Dinshah Health Society, provides the most detailed clinical protocols for those interested in Spectro-Chrome methods.

Frequently Asked Questions
What is color therapy?
Color therapy (chromotherapy) uses specific wavelengths of visible light to influence physical, emotional, and energetic states. It has roots in ancient healing traditions and was systematised in the modern West by Dinshah Ghadiali (Spectro-Chrome system, 1920s-1930s) and Theo Gimbel (Hygeia system, UK).
What are the seven chakra colours?
The seven chakra colours are: Root (red), Sacral (orange), Solar Plexus (yellow), Heart (green), Throat (blue), Third Eye (indigo), Crown (violet or white). Each corresponds to a specific light frequency and chakra function.
What is Dinshah Ghadiali's chromotherapy?
Dinshah Ghadiali developed the Spectro-Chrome system in the 1920s, using filtered coloured light projected onto the body for specific conditions. His 1933 three-volume encyclopaedia provides detailed protocols. While persecuted by the AMA, his system attracted significant medical attention and is still used by practitioners internationally.
What is Theo Gimbel's contribution to colour therapy?
Theo Gimbel (1920-2006) founded the Hygeia Studio and College of Colour Therapy in the UK, synthesising Steiner's spiritual science, Goethe's colour theory, and clinical colour therapy. His books "Form, Sound, Colour and Healing" (1987) and "Healing with Colour and Light" (1994) remain foundational texts in British colour therapy training.
What is the science behind color therapy?
Red light photobiomodulation is FDA-cleared for some tissue healing applications; blue light therapy is clinically proven for neonatal jaundice and seasonal affective disorder; research by Burstein and colleagues at Harvard found green light reduces migraine pain sensitivity. Different wavelengths interact differently with biological tissues through measurable physical mechanisms.
How does red relate to the root chakra?
Red is the longest visible wavelength (620-750 nm) and lowest visible frequency, associated with physical vitality, survival instinct, and groundedness. These qualities align with the root chakra's governance of physical survival and earthly connection. Chromotherapy uses red light to stimulate circulation and physical energy.
What does green colour therapy do?
Green (495-570 nm) is the middle wavelength, associated with balance, harmony, and the healing principle. It corresponds to the heart chakra's qualities of compassion and connection. Ghadiali used green as a universal harmoniser. Research suggests green light may reduce pain sensitivity through opioid pathways.
Can I practise color therapy at home?
Yes. Home practices include: colour breathing meditation; coloured light environments; wearing colours aligned with the chakra you want to support; solar-charged water in coloured glass; and colour art therapy. These are gentle, low-risk practices that complement but do not replace professional healthcare.
What is Goethe's colour theory and how does it relate to healing?
Goethe's "Theory of Colours" (Farbenlehre, 1810) described colour as a qualitative phenomenon of light-darkness interaction, with each colour carrying specific psychological and spiritual qualities. Rudolf Steiner developed Goethe's theory into a broader spiritual framework that directly influenced Theo Gimbel's practical colour healing work.
How does Rudolf Steiner connect to colour therapy?
Rudolf Steiner's lectures on colour (GA 291) describe colour as a spiritual quality: "Colour is the soul of nature and of the cosmos." His colour theory directly influenced Theo Gimbel's Hygeia system and continues to inform Anthroposophical art therapy and environmental design.
