And you are shooting back towards a very bright light source. Always try to get the light source to shine on your subject from at least 90 degrees to the subject...I like it best when it is coming over my shoulder instead of in my face. By over exposing to get the subject that is in shadow to be properly exposed, You set yourself up for purple fringing. The brighter exposure at the point of shadow and dark is in higher contrast and the colors start to split causing some PF or GF. Try using a flash for some of these in the shadow shots.
