Use of Colors

LED Light Therapy Colors & Their Benefits

The patent-pending Visum Light is leading the way in handheld LED light therapy with a keen eye on the future of photobiomodulation (PBM).

In addition to combining red, near-infrared (NIR), blue, and green light all in one convenient device, the Visum Light also allows these colors to be combined, providing even more application options that are only now being studied. Isn’t that exciting?

At its core, the Visum Light’s design is based on some of the first insights of color healing established by pioneers like Roland T. Hunt and his 1971 book, “Seven Keys to Color Healing,” which offers a fascinating look at the topic as it relates to biomedical, psychological and metaphysical applications.

In addition to this research, the Dinshah Health Society has continued the work that Dinshah P. Ghadiali started back in 1920, when he originated the Spectro-Chrome Institute. This was followed by the Dinshah Spectro-Chrome Institute in 1941 and the Visible Spectrum Research Institute in 1953. This research used colored filters to prove that Spectro-Chrome is effective for a wide range of illnesses, establishing the foundation for polychromatic light therapy — the simultaneous use of multiple light wavelengths.

While thousands of studies and trials over the past few decades have established a solid scientific foundation proving the efficacy of photobiomodulation (LED light therapy), a great deal has yet to be uncovered regarding the incredible potential of LED polychromatic light therapy — but the evidence so far is more than a little promising.

This promise is precisely what makes the Visum Light so unique. As more findings are uncovered, the Visum Light is one of the only devices designed to immediately put these findings into practice. It’s not only the ability to accommodate polychromatic light, but the ability to manually adjust Nogier frequencies and dosing, that make the Visum Light one of the only handheld light therapy devices poised for the future.

With a constant eye on the latest research, we look forward to understanding how the Visum Light will continue to serve patients and users the world over in new and exciting ways.

Below, we discuss the more common photobiomodulation therapy colors (red, near-infrared, blue, green), their most popular applications, and their most widely experienced benefits. We then go on to share the concept of polychromatic light therapy and what makes the Visum Light one of the most unique and innovative handheld light therapy devices on the market today.


Visible Red Light

Red light at a wavelength of 660 nm penetrates tissue to a depth of around 8-10 mm (about 3/8′′), making it extremely beneficial for treating problems close to the surface of the skin and particularly effective in accelerating healing, including:

Red light — along with all the Visum Light’s colors — has been proven to be one of the safest, most natural, drug-free and non-invasive ways to promote healing, control pain, increase circulation and accelerate healing. We like to call it the “Great Energizer.


Near Infrared Light

Near Infrared (NIR) light at a wavelength of 810nm is not visible to the naked eye. It penetrates to a depth of about 30-40 mm (1.2′′ to 1.4′′), which makes it extremely effective on deeper structures such as bones, joints, deep muscles and bursa. NIR is also being tested for Transcranial Photobiomodulation (t-PBM) for a variety of brain-related conditions like dementia, traumatic brain injury, depression and more.

Near Infrared light is one of the safest therapies on the market today. It reduces the sensitivity of neural pathways and causes the body to release endorphins that provide a nontoxic, natural form of pain relief. Unlike ultrasound and electrical stimulation, near infrared technology is so gentle that patients can use it frequently without causing more damage to injuries or other chronic pathologies.

Although both red and infrared wavelengths penetrate to different depths and affect tissues differently, their therapeutic effects are quite similar.


Blue Light

The blue light has been called the greatest antiseptic in the world due to its antibacterial and anti-fungal properties. At a wavelength of roughly 410 nm, it serves two purposes. The first is to soothe and cool the skin and stop the process of a contusion — much like ice does — which is why we have coined it “Ice in a Light.” The second is the anti-bacterial and anti-fungal properties this wavelength offers which intentionally includes some UV light, so we also like to call this color the “Great Antiseptic.”

In addition to Blue light’s ability to help alleviate a variety of common physical conditions and skin related issues, it has also been found to have a great deal of potential treating symptoms of depression.

Light therapy elicits a photo-chemical reaction in your body’s cells instead of a thermal response, so there’s virtually no pain or discomfort, with the overwhelming majority of patients and users reporting little to no side effects whatsoever.


Green Light

The green light, or as we call it, the “Great Balancer,” can improve a variety of common issues related to burns, migraines, wound healing and more, helping bring patients and users to a more stable, grounded place both physically and mentally.

Perhaps the most exciting application of the green light is how it has been shown to reduce pain and improve the quality of life for fibromyalgia patients, which may help alleviate additional symptoms associated with the disorder, like fatigue, poor sleep, memory issues and mood issues.

Similar to the red light, the green light has been shown to be an effective wound healer, especially for those with diabetic wounds. Penetrating to a depth of approximately 2.5 mm at a wavelength of 535 nm, it has also been found to provide effective treatment as an anti-inflammatory for burns, helping to accelerate healing and reduce scarring. And its ability to reduce the intensity of episodic and chronic migraines further shows how the “Great Balancer” can bring a great deal of relief to patients and users of all kinds.


Polychromatic Light Therapy – Additive Colors

Polychromatic light therapy, also known as PLT, refers to the use of more than one color in light therapy. By using light of different wavelengths simultaneously, one can receive a wider range of benefits in approximately the same amount of time, thanks to the synergistic effects found with certain color combinations.

Novel treatments are being discovered and studied, expanding on established research and opening up the potential for Photobiomodulation (light therapy) to provide an even more remarkable array of application options than previously believed.

The Visum Light uses additive colors, combining the three primary colors — red, blue, and green — in ways that combine to offer additional colors. Perception of color is limited to the visible spectrum. Conversely, when all three primary light colors are mixed in equal proportion, the result is white light. Red and blue create magenta, red and green create yellow, and green and blue create cyan (also known as turquoise).

By using additive colors, the body receives both the benefit of each individual color as well as the combined color the eye sees. Light therapy colors in the Visum Light each have their own healing properties and can be used independently or combined with another.

The ability to combine colors using the Visum Light device is one of its most profound benefits. In addition to the value received by combining the visible wavelengths of red, blue and green, the Visum Light also provides the ability to add Near Infrared lightwaves. Although these wavelengths are not visible, they are extremely valuable in supporting the gifts of the visible wavelengths and are capable of much deeper penetration.

Let’s take a look at the additive colors of the Visum Light:


Magenta Light

A combination of red light at a wavelength of approximately 660 nm and blue light at around 410 nm, magenta combines the healing powers of red with the cooling qualities of blue. One particularly exciting area of study is its effectiveness with angiogenesis — the growth of new blood vessels. This treatment can help provide much-needed blood flow to damaged areas, helping to heal wounds and scars, and improve circulation. Applications include:

Magenta’s ability to improve circulation can help regulate blood pressure and may improve function of the heart, kidneys and adrenals as well. We’ll be keeping a close eye on new data as it develops for this incredible combination of colors.


Yellow Light

Combining red light and green light, the yellow light makes for a truly powerful wound-healing and related treatment, including scars and burns.

With anti-inflammatory and pain-reduction properties, the yellow light provides a multifaceted approach to healing that vastly improves your quality of life — all while remaining noninvasive and drug-free, with little to no side effects.

What’s more, yellow light has also been found to contain collagen expression properties, showing great potential as an effective new therapy for skin photorejuvenation.

Yellow is also believed to stimulate various organs, leading to more balanced function that alleviates a range of issues. By supporting stomach, liver and intestinal function and stimulating the thymus gland, yellow light eases digestive issues and promotes a host of functions including metabolism, enzyme activation of the liver, stimulating the immune boosting function of the thymus gland and much more. We’re excited to see where continuing research takes us with this fascinating light color.


Turquoise Light

Turquoise combines blue and green light to provide calming balance throughout your system — a mixture of anti-inflammatory and calming properties that can be used to relieve cranial pressure and bring about mental and emotional stability by reducing headaches and migraines, providing more restful sleep and a calmer, more thoughtful mindset.

What’s more, the Visum Light’s turquoise color can also be used to stimulate the vagus nerve — a vital cranial nerve between your brain and abdomen that helps control heart, lung and digestive tract function. This nerve also affects your gut microbiome, which has recently become the focus of intense study as a major factor in your overall health — from your body to your brain.

From the mind and emotions to organs and the all-important gut microbiome, we can’t wait to see more studies on this fascinating color.


White Light

Combining all three primary colors (red, blue and green), the white light provides the most comprehensive simultaneous treatment.

From joint pain and muscle aches to anti-inflammation, scar and wound healing, skin conditions and more, the white light provides all-around healing for a wide variety of conditions and ailments. And with the ability to add NIR light for deeper penetration, you can maximize your relief for arthritis, tendonitis, bursitis and other musculoskeletal issues.

Similar to the blue lights ability to alleviate Seasonal Affective Disorder, white light has also been found to provide relief for non-seasonal major depressive disorder, making it one of the most widely used colors of the Visum Light.

Perhaps white light’s most promising application is as a comprehensive cosmetics treatment, including reducing the effects of aging. By speeding up the skin’s metabolism, white light rejuvenates skin, aiding in the reduction of fine lines and wrinkles, providing a surprisingly effective anti-aging solution that is also free of discomfort and side effects. One of the most versatile polychromatic treatments, we anticipate some exciting research developments in the years to come with the ever-popular white light.
