more clearly separate the ambiguous records
I think we need to more clearly separate the ambiguous records for the unambiguous ones. Toward this end I think we need to do two things.
1. Pleace a space between these two parts of the legend and have the second portion start with a header that states ver clearly "Ambiguous records".
2. Change the colors so that the ambiguous ones are significantly lighter, yet match the hue. Currently the ambiguous records tend to be too bright and often of the wrong hue.
