Rangwali Holi is also celebrated in memory of the immortal love of Lord Krishna and Radha. Once upon a time, Krishna asked Yashoda why he was not as fair as Radha. Yashoda jokingly suggested Krishna to apply color on Radha’s face as it would make her complexion dark too. Lord Krishna, then, played with Radha and Gopis with different colors. Since then, the day is celebrated as the festival of colors.
