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.
Thursday (गुरुवार) is ruled by Planet Jupiter (बृहस्पति). Jupiter corresponds to bright colours like Yellow and Orange.
Wearing yellow and orange on Thursday invokes the blessings of Lord Vishnu since Thursday is Lord Vishnu's favourite day. These colours also recognise the nervous system of human body.
To get the blessings of Planet Jupiter, check out Guru/Brihaspati Yantra on sanatan.in
