That’s the festival of Holi, an Indian holiday that is believed to commemorate the faithfulness of a young man, Prahlada, who continued to worship the god, Vishnu, even after he was ordered to stop by his father. His father commanded him and his aunt, Holika, into a fire that burnt up the aunt but spared Prahlada. The name Holi comes from the unlucky aunt.
Followers of Hinduism offer prayers on Holi and light bonfires to commemorate the story of Prahlada, as well.
The festival can last for a few days and it is generally seen as a time where people do not have to adhere to the strict social code in India but can relax and celebrate.
Although celebrations may vary by region, Holi is an important holiday in India, Pakistan, Nepal, and Bangladesh.
