COLOR:(PART-1): ESSAY BY DR. JOY KUNJAPPU





COLOR (PART-1)  BY DR. JOY KUNJAPPU  

Color adds another dimension to our life in general and imagination in particular. It takes us to a dreamland, although dream itself is not colored. It has a great impact on our psyche, and influences our thoughts and deeds. Many popular products are associated with a color. The national flags are remembered with a color. Even the healing power of color is appreciated. For example, mint green environment is shown to facilitate more rapid post-operative healing. Similarly, light blue surrounding in the conference rooms is believed to allow for greater communications in meetings.




Perception of color has metaphysical underpinnings. It is deep-rooted in the biological processes related to vision. Induction of color into a process is often considered to be a mile-stone event. Thus, color photography, color cinema, color television, color reprography, color fax, etc. were looked upon as epoch-making events in the history of technological advancements. In the modern era, the color printing, especially those based on ink jet technology, has gained popularity owing to the proliferation of computers.




Color is a sensation, a psychophysical response that exists in the realm of mind, consisting of the physical reaction of the eye and the response of the brain to the wavelength characteristic of light. More precisely, the light sensitive lining in retina, which contains cells called cones, recognizes three basic colors - red, green or blue. The brain, in turn, combines these signals from the cones to produce the sensation of color. Another form of retinal cells called rods does not detect color. A primitive form of this theory was put forward by Thomas Young in 1801.
