Ive noticed a problem with the colors also, only the problem is on the main database page. Some systems for Memphis and Shelby County TN were updated, and at the main database page, Tennessee wasn't highlighted in green. This isn't in MyRR its on the main database page.
After clicking on Tennessee, the updates were visable (ie. highlighted in green). Just something to run across to you. During some updates, it will show highlighted in green, and other times it won't.
EDIT: Also, after clicking on Tennessee, The county name, Shelby, also would not be highlighted in green. As stated above, this was right after an update.
