Answer:

Traditionally, Rangoli is an art of decoration drawn on the floor or the entrances of homes. It is thought to bring good luck, prosperity on the house and in the family, and to welcome guests. Some mothers in India do this activity every morning, or on a special festive occasion like Diwali, Onam, and Pongal. ( In my opinion... The Rangoli art is very unique and colorful..)                                                                                                                  

Explanation:

Rangoli is an art form originating in the Indian subcontinent, in which patterns are created on the floor or a tabletop using materials such as powdered lime stone, dry rice flour, coloured sand, quartz powder, flower petals, and coloured rocks. It is an everyday practice in Hindu households, however the colours are preferred during festivals and other important celebrations as it is time consuming. Rangoli are usually made during Diwali or Tihar, Onam, Pongal, Sankranthi and other Hindu festivals in the Indian subcontinent, and are most often made during Diwali. Designs are passed from one generation to the next, keeping both the art form and the tradition alive.
