   Information can also be obtained regarding the color attributes on a
   color display. This is contained in the low byte. The high nibble of this
   byte contains the background color and the low nibble the foreground
   color. Thus a value of 0x17 indicates that the display will print white
   text on a blue background.

   Possible color settings for an IBM compatible color adaptor are:


           0           black
           1           blue
           2           green
           3           cyan
           4           red
           5           magenta
           6           brown
           7           white
