I can also highly recommend the W3 guidelines on enhanced contrast for web
accessibility (SC 1.4.6):

http://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast7.html

As for light grey on dark grey, I find it much less abbrasive on the eye
than "black on white" for a user interface but I would not want to read a
book using it. My current app development uses such a color scheme and
reports so far are positive.

Jacque: The law suit won't get to first base if they can demonstrate they
meet the SC1.4.6 contrast spec!
