Color Light Therapy

Color Light Therapy, also known as chromotherapy, uses the visible light spectrum (i.e., the colors you see in a rainbow) to promote healing.

First made mainstream by NASA’s medical application of red light, this type of treatment has been steadily growing in popularity in recent years.

That said, color light therapy actually has a long history. Ancient healers across many different cultures understood that light (and color) could have powerful healing effects. As imbalances occur in our bodies, our cells can benefit from exposure to specific colors – helping them regain optimal function.

According to chromotherapists, the human body is composed of colors, and these colors are responsible for the functioning of various bodily systems.

In some disciplines, such as chakra healing, the organs and limbs have their own distinct colors. Color can assist with emotional releases and is very useful in relieving stress and anxiety.

  • Red – Activates and revitalizes
  • Orange – Restores and animates
  • Yellow – Fortifies and brightens
  • Green – Balances and relaxes
  • Blue – Soothes and calms
  • Indigo – Purifies and focuses
  • Violet – Inspires and supports

Medical applications of chromotherapy

While ancient healers and mystics were some of the first to use chakra colors to restore balance to the body, modern-day science is finally catching up.

Various forms of light therapy are now widely used in fields such as dermatology, pain management, mental health, joint & muscular issues, and more.

On the technical side, light travels at different wavelengths. Red is at the top of the spectrum, traveling at around 630 nm and above, while violet is at the bottom, starting at around 380 nm.

Depending on its wavelength, light produces different effects on the body. That’s why light therapy is often categorized by either color or wavelength.

Below we’ll look at the different forms of light therapy and which conditions they can treat.

Near-Infrared Light Therapy

Near-Infrared Light Therapy (NIR) generally involves light on a wavelength of 700 nm-1mm. This light is not visible, but the body definitely feels the effects.     ​

The healing effects of near-infrared light only became known with the release of the LED technology. In some medical devices and treatments, NIR LEDs are often used in conjunction with red LEDs.

The benefits of Near Infrared Light Therapy

The major uses for the near-infrared type of chromotherapy are wound healing and cell repair.

NIR can be used to treat:

  • Burns
  • Muscle and tendon sprains
  • Eye injuries
  • Poor circulation
  • Pain – especially arthritic pain
  • Dermatological issues such as aging skin
  • Allergies
  • Diabetic neuropathy

How? NIR has a profound effect on the body. This type of light boosts enzyme activity to stimulate metabolism and also stimulates mitochondrial function to boost ATP (our energy source for all body processes).

It also increases DNA synthesis for cellular reproduction and helps repair damaged cells.

Red Light Therapy (620-750 nm)

Red is considered a hot color and has a stimulating effect, both physically and mentally. It is associated with power, energy, and vitality. Red is essential for physical and emotional transformation.

Red light restores depleted energy and nourishes adrenal functions. In addition, it helps combat lethargy and congestion.

Red light therapy stimulates circulation as well as the muscular and cardiovascular systems.

The benefits of Red Light Therapy

Red light therapy treatment can help with:

  • Wound healing
  • Burns
  • Skin repair and the effects of aging
  • Collagen formation (to help smooth wrinkles)
  • Preventing and reducing scar tissue
  • Increasing blood flow and aiding poor circulation
  • Regenerating the blood
  • Helping with anemia by building hemoglobin
  • Energizing and relieving congestion of the liver
  • Stimulating acupuncture points
  • Strengthening the flow of energy to the kidneys
  • Activating hormones – red light stimulates the pituitary, which starts a cascading effect on other organs and glands
  • Stimulating the production of adrenal hormones
  • Increasing the production of endorphins and enkephalins (mood-elevating and pain-reducing neurotransmitters)
  • Relieving pain in bone and muscle
  • Stimulating sensory nerves, which heighten the senses of smell, sight, taste, touch, and hearing

Much like NIR, red light acts within the cells, stimulating that all-important ATP and increasing RNA/DNA synthesis for cellular reproduction and repairing damaged cells.

Red light is used to help treat:

  • Anemia
  • Asthma
  • Arthritis
  • Bronchitis
  • Chronic Coughs
  • Constipation
  • Eczema
  • Glandular dysfunction
  • Fatigue
  • Listlessness
  • Frostbite
  • Head congestion
  • Paralysis
  • Pneumonia
  • Wounds and inflammation

Despite all the positive progress, red light therapy is not suitable for everyone. This type of treatment should be avoided if you have a fever, hypertension, or nerve inflammation. It should also not be used on open wounds or for patients with mental health issues.

Orange Light Therapy (590-620 nm)

Orange is the color of joy and happiness and can enhance both mental and physical energy.

A warming color, orange is used to help balance problems with the kidneys, the large and small intestines, the lower spine, and sacroiliac joints.

Orange can also relieve nervous tension, arthritis, fear, and loss of appetite (especially when related to depression).

There is some evidence that exposure to orange light for a brief period in the morning will help overcome feelings of lethargy.

The benefits of Orange Light Therapy

Exposing the body to orange light can have the following effects:

  • ​Relieves muscle cramps and spasms – including menstrual
  • Strengthens the lungs
  • Strengthens the kidneys
  • Improves the assimilation of food through the effects on the spleen and pancreas
  • Relieves gas and soothes irritable bowel and the digestive tract
  • Relieves hiccups
  • Strengthens the immune system
  • Increases pulse rate without affecting blood pressure
  • Stimulates appetite
  • Stimulates the thyroid gland

Orange light can be used to help treat:

  • Arthritis
  • Asthma
  • Bronchitis
  • Colds
  • Depression
  • Fatigue
  • Gallstones
  • Gout
  • Underactive thyroid (Hypothyroidism)
  • Kidney conditions
  • Lactation (stimulation)
  • Menstrual issues
  • Respiratory diseases

Orange light should be avoided if you are experiencing any type of anxiety disorder.

Yellow Light Therapy (570-590 nm)

Due to its association with the sun, yellow is considered a bright and cheerful color.

It’s associated with the Solar Plexus, thus being beneficial in balancing the digestive system – the liver, gallbladder, pancreas, spleen, and stomach.

Yellow is also associated with the adrenal glands, nervous system, and muscles. In addition, it activates the lymphatic and immune systems. It is used to heal arthritis and stimulate eye and ear functions.

It can also be used to strengthen the nervous system and assist metabolism.

The benefits of Yellow Light Therapy

  • Rejuvenate the skin – this type of light builds collagen to increase elasticity and reduce wrinkles and other signs of aging
  • Build and tone the motor nerves to energize muscles
  • Aid mental concentration
  • Stimulate and cleanse the liver, intestines, and the skin
  • Activate the lymphatic system
  • Promote digestion
  • Stimulate the immune system
  • Fortify the hormonal system
  • Expel parasites

Yellow light is used to help treat:

  • Arthritis
  • Constipation
  • Diabetes
  • Digestive problems
  • Dyslexia

  • Lymphatic congestion
  • Muscle atrophy
  • Pancreas imbalances
  • Paralysis
  • Sciatic nerve pain

Avoid yellow light if you’re suffering from diarrhea, fever, heart palpitations, neuralgia, or extreme stress.

Green Light Therapy (495-570 nm)

Green is a balancing color. It has a sedating and cooling effect, which helps reduce the swelling and inflammation of joints and tissues while calming the body.

This color influences the heart, breasts, lungs, upper back, endocrine (chemical messenger), and circulatory systems. Green-argon lasers are often used for delicate diabetic eye surgery because green light tends only to affect the blood vessels, leaving other sensitive portions of the eye undamaged.

The benefits of Green Light Therapy

Green light can:

  • Act as a detoxifier
  • Be used as a disinfectant or antiseptic – has a germicidal and anti-bacterial effect
  • Stimulate the pituitary gland
  • Help the sympathetic nervous system, relieve stress in the blood vessels
  • Help dissolve blood clots
  • Build muscle, bones, and other tissues
  • Function as an aphrodisiac and sexual tonic
  • Strengthen the immune system

  • Laryngitis
  • Liver conditions
  • Whooping cough
  • Ulcers

Blue Light Therapy (450-495 nm)

Blue is a cool color and has a relaxing effect on the mind and body. Blue light therapy is often used to help boost morning energy levels as the wavelengths help set circadian rhythms.

Blue is optimally suited to soothe the throat and helps with imbalances in the thyroid and parathyroid glands. It also helps with neck and shoulder tension as well as problems with the teeth and gums.

In color therapy, Sky Blue is used for bronchial issues. Sky blue is a calming color that facilitates the breaking down of emotional barriers. It aids in sleep and relaxation, soothes skin irritations, and relieves itching and pain.

The benefits of Blue Light Therapy

It is also used for burns to speed healing, cool, and soothe.

Blue light:

  • Has anti-inflammatory qualities
  • Increases metabolism and builds vitality
  • Promotes growth
  • Has a tonic effect on blood
  • Calms nerves
  • Has an astringent effect – meaning it can shrink tissues and dry up secretions
  • Can reset the biological clock when applied behind the knees. Blue light exposure is helpful whenever the body needs to adjust to different time zones or for shift work.

Blue light is used to treat:

  • Acne and blemishes, including skin eruptions from measles and chickenpox
  • Baldness
  • Burns
  • Colic
  • Diarrhea and dysentery
  • Fever
  • Headaches and migraines

Do not use blue light if predisposed to macular degeneration, if you are experiencing cold symptoms, or if you have high blood pressure.

Indigo Light Therapy (420-450 nm)

Indigo is a colder color that is used in all conditions involving an excess of heat. Peaceful and calming, it has a relaxing effect on the mind and body.

Indigo is often used for restlessness and pain. It helps to calm skin eruptions as well as aids in the treatment of bacterial infections.

Indigo is beneficial for imbalances in the pineal and the pituitary glands, sinuses, eyes, ears, and nose.

The benefits of Indigo Light Therapy

Indigo light:

  • Has an anti-bacterial and anti-inflammatory effect
  • Helps with various skin conditions
  • Speeds healing (especially boils and skin ulcers)
  • Calms the nervous system
  • Reduces swelling of wounds
  • Has an astringent effect – similar to blue light, Indigo shrinks tissues and dries up secretions

Indigo light can be used to help treat:

  • Ear, Eye, and Nose conditions
  • Hearing problems
  • Hemorrhages
  • Insomnia
  • Learning disorders
  • Sinus problems
  • Skin conditions
  • Varicose veins

Avoid indigo therapy if you are predisposed to macular degeneration or have high blood pressure.

Violet Light Therapy (380-450nm)

Violet is another one of the more cooling colors. It has a soothing effect. Violet helps with imbalances in the pineal and pituitary glands. It also helps soothe the nervous system and mental functions.

The benefits of Violet Light Therapy

Violet color:

  • Supports and calms the central nervous system
  • Helps improve memory

Color combinations

Sometimes the best results are seen by combining colors, using their different effects for more holistic healing.

Red and Blue Light – Acne

Alternating red and blue light can be used to clear up severe cases of acne and skin welts. The blue light attacks the bacteria causing acne, while the red light stimulates collagen and elastin to renew the skin.

Red and Amber – Rosacea

If you have burning, itching, acne, rosacea, or broken capillaries, always start with red light.

However, for redness or broken capillaries, you may want to try a combination of red and amber light.

Rosacea, in particular, is suited to this type of treatment. As with other inflammatory conditions, irritated skin can really benefit from the application of red light.

Orange and Blue Light – Glands and Hormones

Alternating Orange and Blue light can help balance the endocrine (chemical messenger) system.

Green – All Conditions

Green is often used prior to the application of other colors for more effective results. The only condition where you’ll want to avoid green (and possibly blue) is rosacea – as this is an inflammatory condition best treated with red light.

  1. You do not make it clear as to how the combination colors are used. Are they color filters and stacked upon one another …. are the colors used separate at different times …. are there two different color devices used at the same time?

  2. What devices are available with these light choices? People may need to treat more than one issue so maybe need one device with different color choices.

  3. Hello. I am asking a second question after just reading. the
    f.a.q. s. It seems that people might benefit from the infrared and red, red alone, or red and blue. Then, if they feel something more or different is needed, try the device with the other ( single colors or two colors combined).
    The writing also stated that it is possible to get too much red light therapy and that long term use of red light therapy can be aging and it cause oxidative damage. I thought that if you follow the distance and treatment or session time (a.k.a 16 minutes or whatever it is for that device) it wouldn’t cause harm. How can you know what is too much? Some people claim to use their red and or infrared devices daily for the recommended treatment session time. Thanks.

    • Some devices have multiple color filters so that you can use different light options.
      As far as red light beeing harmful you would have to expose to very large doses (hour and hours of continual exposure). If only the recommended treatment times are followed (20-30min daily depending on device strength) there will be no negative effect. Hope that answers your question.

  4. It’s fantastic to learn that red light therapy can help with arthritis pain. My wife is wanting to reduce the pain she’s feeling in her knuckles and she was wondering what kind of therapy she could do to reduce arthritis pain. I’ll be sure to tell her that she should do red light therapy to help with her arthritis pain.

  5. THIS IS AN EXCELLENT PAGE, THANK YOU, all colors are REQUIRED just as the rainbow of the sun colors are requird by our cells, let NOONE tell you color therapy is not good and necessary, excellent information hope people listen to this
