We Gujaratis celebrate every festival with great pomp and festivity. Dhuleti or Dhuli Padvo is celebrated the next day after Holi . It is the second festival after Uttarayan in January which we all await. Literally, Dhuleti means throwing of mud, the practice, which had given way to throwing of vermilion. Although it is not altogether missing in action. Nowadays, a lot of chemicals mixed in colors are used to play Holi which sometimes takes away the fun of Dhuleti and makes it dangerous at times. However, there has been a growing consciousness for natural colors and dyes. I'd like to know more about natural Holi colors and how to judge the purity of the colors of Holi. The other day I saw 'Rangeela' Holi colors from the colour pencils and poster color brand 'Rangeela'. Should we buy Branded colors only?
