Colored Light Therapy

What Is Colored Light Therapy?

Colored Light Therapy (sometimes called chromotherapy) is the practice of using specific colors of visible light to influence mood, energy, physiology, and emotional balance. It sits at the intersection of ancient healing traditions and modern neuroscience, but it’s important to separate evidence-based uses from more holistic or energetic claims.

Colored Light Therapy exposes the eyes, skin, or environment to distinct colors (wavelengths) of visible light, each believed to have different psychological and physiological effects.

Unlike photobiomodulation (red/NIR therapy), colored light therapy:

  • Uses visible colors across the spectrum

  • Often targets the brain and nervous system via the eyes

  • Is commonly used for mood, circadian rhythm, focus, and emotional states

How It Works (what science actually supports) and How It May Help...

1. Visual System → Brain

Light enters the eye and activates:

  • Retinal ganglion cells

  • The hypothalamus (circadian clock)

  • Neurotransmitter pathways (serotonin, melatonin, dopamine)

​

This is why light color and timing can affect:

  • Sleep

  • Alertness

  • Mood

  • Stress response

​

2. Psychological & Perceptual Effects:

Colors influence:

  • Arousal levels

  • Emotional states

  • Cognitive performance

(Some effects are cultural/psychological; others are biologically mediated)

​

Common Colors & Typical Uses Colored Light Therapy 

⚠️ These are general associations. Only a few have strong clinical backing.

​

🔵 Blue

Best-supported scientifically

  • Increases alertness

  • Suppresses melatonin

  • Improves attention and reaction time

  • Used for Seasonal Affective Disorder (SAD)

⚠️ Overuse at night can disrupt sleep

​

🔴 Red

  • Calming for the nervous system (non-alerting)

  • Doesn’t suppress melatonin much

  • Often used in evening environments

  • Less stimulating than blue

(Note: this is different from red photobiomodulation, which targets cells directly)

​

🟢 Green

  • Stress reduction

  • Migraine relief (some clinical evidence)

  • Emotional balance

  • Visual comfort

​

🟡 Yellow

  • Perceived as uplifting

  • Linked to optimism and mental clarity

  • Limited scientific backing beyond psychology

​

🟣 Purple / Violet

  • Often associated with creativity and introspection

  • Mostly symbolic or experiential rather than clinical

 

Clinical vs. Holistic Use

Evidence-Based Applications

✔ Blue light for SAD
✔ Green light for migraine modulation
✔ Light color manipulation for circadian rhythm regulation

​

Holistic / Alternative Uses

  • Chakra balancing

  • Emotional “energy” alignment

  • Spiritual or meditative practices

These aren’t strongly supported by biomedical science but can still have subjective or placebo-driven benefits.

​

Safety notes

  • Avoid intense blue light at night

  • Use caution with photosensitive conditions

  • Therapeutic lamps ≠ lasers (lower risk)

​

Bottom line

Colored light therapy:

  • Does affect the brain and mood

  • Is strongest for sleep, alertness, and emotional regulation

  • Becomes less scientific as claims move toward “energy healing”

​

It can be useful, especially when paired with:

  • Circadian timing

  • Intentional environment design

  • Mindfulness or therapy practices
