Colour therapy can be administered in various ways. In earlier times, gems were used for colour therapy. Presently, several methods for administering colour therapy are practised worldwide.

Colour therapy includes breathing exercises conducted when the eyes are looking at a specific colour are believed to help the body absorb colour vibrations.

Crystals are available in various colours. When light passes through them, the corresponding colour light is obtained, which can be used for therapeutic purposes.

Coloured garments are another way of administering colour therapy. By covering an organ that needs vibration with a coloured cloth, the desired energy can be passed on to a person.

Coloured water – also termed ‘solarised' water – is another popular method of colour therapy wherein coloured bottles containing water are exposed to sunlight for some time.

Ordinary, cool, white fluorescent lamps have an unbalanced spectral distribution and distort other colours, straining the eye and the system. Now, full-spectrum fluorescent lamps are manufactured abroad, which give light in the same colour temperature as that of sunlight. This exactly matches the bright, white sunlight one sees during the day. Exposure to this light has reportedly brought relief in various types of glandular disorders, insomnia, fatigue, depression, Alzheimer's disease and other ailments.

Blue light is found to be effective in the treatment of rheumatoid arthritis, a joint disorder that has so far remained elusive to cures by modern medicine. There is no proven medicine except a recommended regimen of vitamins, painkillers and physiotherapy to check the progress of this disease.

The colour pink has been found to be a tranquilliser and has a calming effect within minutes of exposure. Hostile and aggressive people can be turned into more agreeable types and it is almost an acknowledged fact that in pink surroundings, people cannot be aggressive, even if they want to, because the colour saps their energy.

Colour therapy, is the best way for people suffering from the learning disorder, dyslexia, respond favourably to colour therapy. Doctors have found that having these children put on tinted glasses could make them see letters properly. He Britain Medical Research Council has confirmed this in 1993. In Britain , an Intuitive Colour Meter is developed to select the right colour glass for people suffering from dyslexia.

It is believed that the pineal gland may be behind the manifestation of this unique ability. The pineal gland produces two hormones called melatonin and serotonin. Melatonin is an important chemical which helps animals respond to light and synchronises their body reactions to the daily cycle.

Serotonin is another very important chemical of the brain that is responsible for behavioural patterns. During a span of 24 hours, serotonin is produced during the day and melatonin during the night. Depression appears to be linked with melatonin levels. Naturally, sunlight alleviates this problem by controlling melatonin release

Specific colours appear to affect specific diseases. Eruptive diseases respond better in a room with red windows. Similarly, people under stress or depression recover rapidly when they are placed in rooms with red light. Pain is relieved when patients are subjected to flashing and coloured lights.

Scientists believe that the brain itself is colour sensitive and responds to different frequencies of various colours. Using blue colour, for example, can effectively cure sleep problems. Violet light induces relaxation, reduces stress and chronic pain.

Research on colour therapy is continuing in various parts of the world and several university hospitals abroad have allowed their post-graduate degree students to conduct their thesis research on colour therapy projects. A section of modern medical practitioners believes that colour therapy has a bright future.
