Jyotish Shastra or Vedic Astrology refers to the study of movement of celestial objects and their influence on human life. Jyotish(ज्योतिष) literally means the study of light in Sanskrit and the light refers to the gleam of stars and planets.
As per Jyotish Shastra, each day of the week corresponds to a planet as well as gems and colours.
Sunday (रविवार) is ruled by Sun (सूर्य).
Sun corresponds to Red colour.
Red colour signifies energy and vigour but also aggression and fierceness. Wearing Red or Maroon clothes on Sunday enhances one's personality and invokes Sun's blessings for health and positivity.
