the canonical way to do it in DOS mouse drivers was to
xor the color with 7, i.e., leave brightness/blinking bit untouched
and just invert the CGA-style color.
This way, it's guaranteed to be distinct from color of text.
(black on white -> white on black, yellow on red -> blue on cyan, etc.)
by the way, while we are talking syscons, Soren, what ever happened
to my `invert border color in cyrillic mode' and `visual bell by
blinking border' patches I sent to you in, what, 1996? Should I dig
them up and port to 2.2.6??
