The visible Sunlight which is a combination of seven colors gets manifested in violet, indigo, blue, green, yellow, orange and red (VIBGYOR). These colors travel in different wave lengths with varying energy intensities.
The Sunlight is the source of all life in the biosphere and it is responsible for all the biogeochemical cycles in the environment of the earth which sustains all the plant and animal life including the life of human beings. The main driver of energy is the Sun from where the color waves originate.
In all astrological treaties, the significance of color was emphasized for astrological remedies.
