Everything we see has an effect on our psyche. Every color we look at influences our thinking processes. To show respect to this fact, astrology has matched certain colors (energies) with each of the nine planets, and it prescribes these colors to intensify planetary influences that our charts introduce as being beneficial for us. Every color tends to bring some flavors of the associated planet in our lives. While white (Moon) may signify peace and purity, red (Mars) may signify aggression or action; while grassy green (Mercury) may signify wit and precision, yellow (Jupiter) may signify optimism and wisdom.
Unsurprisingly, some colors are to be avoided. If a person has an afflicted Saturn and its energy supposedly obstructs normal functioning in life, the colors black and navy blue may be avoided while choosing attire. This way our mind will not have to face a self-imposed increase in saturnine signals like gloominess and selfishness. On the other hand, if our charts show that we have learned to properly utilize saturnine energies, these shades may be prescribed. With the positive side of Saturn surfacing, black will not signify gloom but discipline and hard work.
In remedial astrology, while colored gems are prescribed to strengthen a planet that is naturally good to us (a benefic), the concept is extended to “donation” (daan) of colored objects to please an unfavorable planet. If a person has difficulties harmonizing Martian influences in life, one would be expected to donate red colors, say red lentils or clothes to a fellow being. Just like wearing clothes (or gems) of a specific color represents accepting the energy of a certain planet, donating items of a color represents renouncing the less harmonious color-coded frequencies.
Everyday life shows how some of these Vedic principles are embedded in Indian culture. As an example, saffron remains the all time favorite color of the Hindu seeker. One reason is its synchronization with Jupiter, the Guru, who is expected to bless us with learning, traditional knowledge, and spiritual rise. But with changing times, instead of the yellowish shades, students mostly wear navy blue and black, the shades of Saturn, who is the lord of Capricorn — the debilitation sign of Jupiter and the sign of the natural zodiac that "controls" professional matters. Although these shades may not be astrologically conducive to traditional learning, they certainly attune with career-oriented education.
