Colours can be produced either by allowing white light to pass through a medium like water or a prism, or by using other methods to produce coloured light, such as using bulbs or letting the light pass through coloured window panes. However, when it comes to obtaining colourful material objects, we have to mix pigments or dyes, whether these are derived from natural resources or prepared artificially using synthetic chemicals.
All colours, whether obtained by combining spectral lights, used as paints in artwork, or as dyes for fabric, emit vibrations of various frequencies. These vibrations create feelings of warmth or coolness. The wavelength of red is the longest of all spectral colours, producing the lowest vibration. The wavelength of violet is the shortest and causes the highest vibration. The frequency of red waves produces heat, blue gives a cooling effect, and green is known for its moderation and balance. The density of red confines movement and lowers the rate of its vibration, whereas blue, due to its lightness, brings openness to the atmosphere.
Every colour generates a different feeling. Red, for instance, gives a burning sensation. Orange appears heat-giving, yellow gives a sense of warmth, green is neither hot nor cold, and maroon gives a sting with coolness. When we try to feel colours, some seem stingy; some bite, hurt, hit, smash, or even feel like a pat. Generally, people do not think about colours. We do absorb impressions from pictures, but we rarely notice the disposition or temperamental effects of colours.
Experiments have established that patients suffering from insomnia, sleeplessness, tension, and strain can find relief if exposed to violet, blue, or turquoise. Red, orange, and yellow have proven helpful in overcoming lethargy and fatigue.
Experts in chromatology suggest that pink can suppress feelings of aggression and antagonism when the patient is kept in a pink environment. Pink has proven to soothe the nerves and tissues. These calming effects have led authorities to use pink in prisons to aid in reform and rehabilitation. It not only subdues anger but is also helpful in resolving issues stemming from family feuds or business worries, as people tend not to react aggressively under its influence. Even blind individuals feel more at ease in pink-painted rooms. Due to its soothing effects, pink is considered one of the most lovable colours.
Colours are broadly classified into three categories: hot, cool, and moderate. Red, orange, yellow, and their shades are hot colours. Blue, sky blue, and violet are cool colours. Green is neither hot nor cool. If a disease results from excessive heat in the body, cool colours are applied—for instance, blue for fevers or burns. Conversely, if the disease is due to coldness or lack of internal warmth, hot colours are used—for example, red for low blood pressure or paralysis.
The properties of colours can be studied under two main headings: psychological and physical.
Red is found in iron, zinc, copper, potassium, oxygen, sugar beet, radish, spinach, tomato, red cherries, and other red-skinned fruits. It is associated with blood and the bloodstream. It cancels the effects of blue and its shades. Psychologically, red is linked with courage, enthusiasm, love, and affection. When relationships are damaged due to rudeness, unmet expectations, or failed plans, red dominates the mental centre. When the red centre in the brain is overactive, everything appears reddish. A faded red centre suggests emotional distress or unhealthy attachments. People with a moderate presence of red tend to be helpful, proactive, and caring. They generally live healthy lives but may become overweight due to their emotional connection with food and comfort. Everyone experiences a phase in life when red dominates, especially during adolescence. A rusty hue of red is common among boxers. People with a red-dominant aura often pursue physical health and bodybuilding.
Red stimulates emotion, stirs the senses, and evokes passion. It represents power, vitality, and excitement. Positively, it inspires strength, joy, and love. It is the primary colour of fire. Deep scarlet stimulates animal instincts, crimson signifies suffering, and gentle pink gives rise to maternal love. Negatively, red can bring fear, uncontrolled passion, lust, anger, agitation, and cruelty. It is recommended when vitality is low or blood circulation is weak.
Although it’s difficult to accept, everything on Earth exists in vibration. Life forms and objects shift from one vibration to another. Colours can be therapeutic or harmful depending on circumstances. For example, red excites a bull when waved, signals “stop” in traffic, and keeps you warm when worn. In labs, fruit flies breed rapidly in red boxes but not in blue ones.
Doctors use red as an arterial stimulant. University of Texas researchers found that athletes concentrating on red before performance show increased muscle strength. Red can cause blushing by increasing blood flow to the face.
Physically, red has the slowest vibration and the greatest warmth. It stimulates creativity and activates the adrenal glands, sensory nerves, and cerebrospinal fluid. It energizes the liver and left cerebral hemisphere. In anemia or leukemia, red light on the spine increases red blood cells. It also restores tissue function in paralyzed limbs. Red rays break down salt crystals in the body, producing ions that carry energy. They stimulate hemoglobin production and improve circulation. Conditions treatable with red are discussed later, but it is contraindicated for emotional disturbance, hypertension, fever, and inflammation.
Orange is found in iron, calcium, nickel, and orange fruits like carrots, apricots, and mangoes. It supports the nervous and respiratory systems and nullifies negative effects of dark blue. People with dominant orange enjoy active games and become restless if forced to delay. They’re sociable, informal, and like gatherings. Orange-dominant individuals are early risers and energetic. It enhances willpower and creativity but in excess can cause nervousness. Orange is hot due to its red-yellow mix. It helps thyroid function, calcium absorption, lactation, digestion, and respiratory health. It treats asthma, cough, pneumonia, epilepsy, gout, arthritis, and more. It supports the spleen, pancreas, and mental clarity. It dissolves tumors and treats menstrual issues. It is contraindicated in insomnia, fever, or over-excitement.
Yellow is present in gold, sodium, carrots, bananas, and lemons. It’s linked to the digestive system and counters violet and purple effects. As a primary colour, it’s used in creating orange and green. In light, it’s made by mixing red and green. Yellow brings joy, wisdom, and intuition. Its golden shade symbolizes spiritual perfection. Yellow encourages learning, and those under its influence often become scientists or entrepreneurs. Overuse may cause mental stress or selfishness. People with excessive yellow tend to be materialistic. Yellow stimulates the mind, aids focus, and helps in learning. Yellow rooms benefit children with learning difficulties.
Physically, yellow treats digestive issues, liver disorders, and diabetes. It acts as a laxative and nerve calmer. It eliminates parasites and stimulates bile flow. It energizes the digestive tract and purifies the blood. Contraindicated in fevers, heart palpitations, and inflammation.
Green is found in nickel, cobalt, chlorophyll, and green-skinned fruits. It is chemically neutral and linked to the skin. It cancels the effects of red and helps with inflammation and kidney issues. Green is healing and calming. It reduces tension and supports emotional well-being. In excess, it can lead to emotional instability. Yellow-green promotes generosity and detox. Spring green symbolizes renewal and joy. People under green are affectionate, gentle, and thoughtful. Teachers and caregivers often radiate this colour. When excessive in the yellow centre, it can cause over-concern and loss of appetite. If it’s deficient in the mental centre, it leads to selfishness. In the throat, too much green makes a person overly soft-spoken; too little causes harshness.
Physically, green builds tissues, reduces blood pressure, and disinfects wounds. It helps with ulcers, insomnia, infections, and high blood pressure. It treats skin conditions, wrinkles, and liver issues.
Sky blue is found in aluminum, zinc, and certain fruits. It is associated with the upper body and is the coldest colour. It balances red and orange. Blue symbolizes truth, calmness, and spirituality. It is sedative and often used in psychiatric hospitals and prisons. Excessive blue can be tiring or depressing. It soothes quick tempers and promotes balance. It calms manic-depressive tendencies but prolonged exposure may lead to lethargy.
Physically, blue lowers metabolism, soothes inflammation, and contracts muscles and blood vessels. It treats burns, fever, cataracts, insomnia, and heart issues. It is not recommended for colds, gout, or rheumatism.
Indigo, created by mixing red into sky blue, is cooling and electric. It stimulates the parathyroid and purifies blood. It reduces excessive bleeding and supports psychic development. It controls sensory and brain activity, repairs cells, and eliminates toxins. It is effective in purifying blood, treating mental illness, convulsions, deafness, and nasal issues. Contraindicated for cold-related conditions or low blood pressure.
Violet is made by combining red and blue. It signifies spirituality, wealth, and creativity. It fades quickly but stimulates higher consciousness. It represents beauty and elevated values. Lack of violet means lack of appreciation for beauty. Da Vinci believed violet enhances meditation. Violet calms the nervous system, controls hunger, and balances potassium and sodium. It treats kidney and bone disorders, mental illness, tumors, and more. Overuse may cause pretentiousness or deceit.
Magenta is formed by adding yellow to violet. People with magenta auras have administrative abilities. It is used where both violet and yellow are required, such as for obesity or diabetes.
White is not a single colour, but a combination of all. It reflects all colours and is considered pure. It softens the intensity of other colours. White is used to treat psychological disorders, high blood pressure, and drug addiction. It purifies and balances emotions.
Black is not a colour but a result of total light absorption. It reflects no visible rays. It is useful in treating conditions involving excess of multiple colours, such as obesity. However, its use requires caution. If symptoms like low blood pressure appear, red or blue should be added to maintain balance.
Gray is produced by mixing black with white. It has a moderating effect and is used where one colour is deficient while others are in excess. It is effective in treating white skin patches. Patients should view a 9×12-inch gray glass for 15 to 20 minutes, two to three times daily.
Brown is formed by mixing black with red and ranges from yellowish to reddish tones. It represents dormant fertility and preservation. It is environmentally soothing and beneficial for internal health. It is often used in packaging to protect against decay.
In every civilization, humans have used colour on physical, mental, and spiritual levels. Physically, colours support health. Mentally, they influence moods. Spiritually, they reveal a world beyond the material—one we enter after death. In that realm, a milky white light can be seen through the third eye. This light maintains its own balance and balances others. People who store this light radiate it and bless those around them. Their belongings are preserved as sacred items.
The subtle vibrations of milky light continue to radiate from the graves of those who carried it in life. It electrifies the atmosphere, uplifts the soul, and fills a person with cheerfulness and deep insight into life and death, purpose, and the Hereafter.
To store this light, one must meditate daily at a fixed hour for 20 to 30 minutes. The goal is to establish a connection with the inner self. When this connection is made, the metaphysical white light begins to descend and transform the soul. It provides protection from worldly problems and grants the ability to bless others, even through mere intention.
