I assume you are talking about the CGA on a PC or Clone.  If so, then
you are out of luck.  There are only 8 background colours.  There are 3
bits for the foreground colour, 1 bit for foreground intensity, 3 bits
for the background colour, and 1 bit for blinking.  If you are using
a PCjr, you can diddle with the colour map to get any of 16 colours 
substituting for any other colour, allowing any background colour (but
still only 8 background colours on the screen at once).
