Colour Theory of Astrology

Astrology uses color association. Specific colors have been assigned to each sign of the zodiac.
Every thing in this universe is composed of Seven Rays of colour. Ancient Indian text, the "Kurma Purana", the seven planets are to be seen as condensations of the seven cosmic rays.
