Holi is a Hindu holiday that celebrates the arrival of spring, love, and fertility. It is also known as the festival of colors, as people gather powdered dye in many colors and throw it at one another.
Holi came from a legend dealing with the god Krishna and his wife, Radha. To understand this story, you need to know that Krishna had blue skin. As the legend goes, Krishna fell in love with Radha. However, he was worried the difference in their skin colors would be a problem. He told his mother about his concerns. She told him to go to Radha and ask her to paint his face any color she wanted. This made Krishna less self-conscious of their skin color differences, and they fell in love. Some lovers continue this tradition by painting their faces the same color on Holi to celebrate their love.
