As the nine nights represent the nine planets, we will be focussing on Navaratri and the nine planets with an account of one or another the planets for nine nights. For the third night of Navaratri, we will take the planet Mars. The third day of Navratri is Sindoor Tritya. The colour for the third day of Navaratri is RED, so we scribe in RED for this third day observance of Navaratri. The Goddess is Maa Chandraghanta.
