I think this phrase is more illuminating:

Several other important findings also resulted from the analysis
including the fact that light-on-dark color combinations were rated the
same as dark-on-light color combinations..

The key is to increase content contrast until it is readable by most of
the target audience. For the rest you rely on providing alternatives
that they can read. A more effective way to make sure it's readable by
the visually impaired is to adhere to the Section 508 standards. That
way those persons can apply their own style sheet that is readable to them.

By the way I have been making incremental changes to the contrast and
other minor elements. Just did not want to pollute the list with an
email for every change. Go visit the page once in a while to see if
things are more to your liking and post with comments.

Neat.. I've done the same in many sites but in the other direction ;-)
It would be possible to provide such visual effects. But without
Javascript it only work on CSS1 compliant browser, i.e. not IE :-\
