This is an annual celebration on the campus of University of Nebraska Medical Center in Omaha.  It is an ancient tradition in India marking the passing of winter into spring. The hardest part of getting this picture is making sure you can be straight on to get faces and colors, but also being down wind so that all the colors don't blow into you camera and get all over you.  Trust me, I learned from that mistake the first year.  That is why I put on my 200mm so I could get far enough back and still get the picture I envisioned.
