In ancient times, there were great halls with coloured glass panels or windows where people would stand and be bathed in the light that filtered in. The practice of colour therapy Followers of this alternative method of healing emphasize that colour therapy should only be performed by experts who know what colour or mixture of colours is required for the cure of an illness. There are no standard rules. Colours that work for one person need not necessarily be as effective for another person. In addition, it is believed that overexposure to certain colours can lead to side effects.
Some therapists ask their clients to visualize colours under the effect of hypnosis.
Other experts make suggestions about the colour of the food a person should eat, the colour of his clothes and even the colour of his surroundings. Solarized water can be used as a healing tonic. In this method, purified water is filled in a clear container of the presribed colour and left out in the sun for a couple of hours. The sun's rays filter through the coloured glass container and energize the water with the vibration of the prescribed colour. The colour red represents vitality, creativity, energy and power.
