Here's my thoughts on this sort of thing...
If someone needs a high-contrast mode in order to see their screen, they
need it for more than just their web browsing. If they have MS Windows,
they have a high-contrast mode selector built in. (Frankly, they do
with other OS's as well.)
I would suggest that you make certain your site works with Windows
High-Contrast Mode in its standard theme. If you include a
high-contrast option within the site, don't necessarily think you need
to go with a black background (again, someone who really needs a black
background will have that for every application through their OS).
White-on-black, black-on-white, or blue-on-white are good choices.
The Contrast Analyzers within the WAT (Web Accessibility Toolbar) will
give you a leg up on whether your existing color choices represent
As for font face and size, I would lean towards a sans-serif font for
on-screen presentation, and not do anything with the size that would
interfere with the OS changing the size/color in various modes.
