It does not realize that it is color, and thus not setting an attribute
in the attribute byte (in this case an 4 bit foreground color value, a 3
bit background color value, and a CGA emulated register "blink bit") means
that the text is invisible.  I believe twiddling bit 5 in the CGA control
register will give you 4 backround bits (changing the interpretation of
the blink bit 8-)).

The blue text comes from the fact that the underline attribute on a
character on a mono screen shows as the color blue on a color screen
(same character color bit pattern).
