Library hexrgb.el has this (`hexrgb-complement') and many other such
utility functions for colors.
Library palette.el provides a WYSIWYG color palette for working with
colors. In the palette, `~' picks the complement of the current color.
Both libraries are on Emacs Wiki and MELPA:

You can see the color palette here:
