White light is actually composed of 7 primary and 2 secondary colors blended together.
The seven colors are red, orange, yellow, green, blue, indigo and voilet. The other
two colors are ultra voilet and infra red. The seven primary colors become visible
in the form of rainbow, but the two secondary colors always remain invisible.
The nine colors are understood to be the cosmic matrix and very essense of the
nine planet, and it is through those colors that the planets radiate their energy
and influence.
The wavelength of colored-light emanating from the nine planet is believed
to watch those radiating from each planet’s corresponding gemstones. ie- the
wavelength of light emanating from the sun is identical to that exhibit ed by a
ruby – both are red. Among all the elements of nature, gemstones constitute
the most condensed form of concentrated color. Gems provide an inexhaustible
source of cosmic color rays.
When colored-light waves are mesured, infra red exhibit longest wave length
and ultra voilet, the shortest.
