Holi is one of the most colorful and celebrated festivals observed across all regions of India. It commemorates the triumph of righteousness and religious devotion over evil and egotism, as depicted in the legend of the demon king Hiranyakashipu being defeated by his devotee son Pralahda with the help of the Hindu deity Vishnu. Holi is celebrated with the spraying of colored dyes and powders, lighting of bonfires, and festivities lasting between 3 to 16 days depending on the region in India.
