[Image-SIG] Font colour.

[Amos Newcombe]

You find the complementary color by subtracting each color band from 255
(assuming 8-bit color). The problem with this is that if your original color
is medium gray, the complementary color will be very close to it and you
will get no legibility. So you have to test for this case and go to some
other color, perhaps black or white.
