I'm having issues trying to use the manage colors settings for contrast control. I've been experimenting with changing the boxes for text and background under the "link colors" column, but I don't understand what the second column of boxes on the right side are. I'm actually trying this as a work around for an issue with visited link colors under the use system settings option--they turn purple against a black background so they're almost unreadable. I've asked about this before with no solution. Thanks for any help Karen F,
