1. Why would you shoot this in JPG? You have one of the best cameras on EARTH, and just turned it into a fancy point and shoot by shooting JPG. Especially under tricky lighting conditions.
2. Purple is a VERY hard color to render correctly. Most stadium lights do not emit the range of color spectrum to properly render purple. So you were likely fighting a battle that could not be won.
