Yes.  8-).  The answer is "whatever you say it is"; setting the foreground
high intensity bit under mono is the same as the blue bit under color.  I
believe you can remap it (I have no Idea how, though).

Well, the attribute clear screen is how it's supposed to act; I'd argue
a problem in ncurses or whatever program's screen handling code (I've
seen the same thing under elm, myself).
