I find that even pink on green or similar works quite better than
white-on-black.  So maybe this is a problem with the suitability of
rendering/antialiasing/gamma correction mechanisms and could be
improved to a point where it is tolerable.

Well, I guess at the time you changed, white-on-black really was not
supported by preview-latex at all.  But the problem remains that
preview-latex, after all, is a WYSIWYG tool, and large departures from
the paper look are not easy to reconcile on the screen.

I think we do a reasonable job.  A more thorough possibility would be
to do this with color transfer functions, but frankly, how do you then
convert a color pie chart from black-on-white to pink-on-green?  Where
does red go?
