Hi Jim, so are you saying that the blue color is because the radiation is
moving faster than the speed of light (in that medium)?  Does this mean
that their is a "blue shift' "as in stars coming at us" that we pick up?  


The propagation of light and of sound both follow the same wave equation.
Cerenkov radiation is the electromagnetic analogy to a sonic boom.
