Good that you found a fix. Still, not much gets my ire than all these grey on white text entries. I have often felt that the ADA should have a hand in this. Unfortunately if they started now, then there would still be all these web sites that already have it.
You even find it at the ADA web site. For you it was accidental and corrected but what could these other, well paid, designers possibly be thinking about when they do this?
