Blue bar shows the health of the current attack, red bar shows the health of the entire boss (as if you lined up all the individual attack lifebars, then shrunk it to fit). I figure that's a lot easier to see how good you're doing at a glance, rather than DMF's extremely thin and hard-to-see default bars...
