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).
