Holi is a Hindu festival which is celebrated on the last full moon day of the Winter season. Holi symbolizes many things – the arrival of Spring to some, while to others it celebrates good over evil. Of course, the arrival of Spring is a harbringer of burgeoning new life and vibrant colors in contrast to the coldness and darkness of Winter.
I just came across this photoshoot featured on DesignSponge.com which captures the colors and spirits of Holi perfectly. You can find the article here.
