This holiday already passed on March 8th, but I recently re-discovered the Holi festival and realized how fitting it was for "Phenomena of Color!" Also called "the Festival of Colors," Holi is a socio-cultural, spiritual holiday celebrated in the spring mainly in India.
This holiday can last 16 days, but on the main day, people are in the streets throwing powders and water of various vibrant hues at each other. All of the markets and bazaars prepare for the event by selling these amazingly bright colors. I would love to be in India during Holi, that must be a crazy colorful experience, visually and culturally.
