I got a CGA card from Jameco or JDR a couple of years ago.  It has both
a monochrome and color composite output jack.  Even if connected to the 
color jack, the monitor will only display color in the LOW RESOLUTION
modes (ie 320x200 and 40 column text).  High resolution and 80column text
are always displayed in monochrome due to the resolution incababilitys of
composite monitors.  There is a potentiometer at the front of my AT mother
board that I also needed to adjust in order to get correct color output.
There may or may not be such a pot on your PC.
