If you've clicked on the member's name for any reason to view their profile or something (in threads, who's online, or PM list), it will change the color of the name. For instance, I clicked on sky's name to view profile from one of her posts here. When I returned, it had changed to a dark green/black color.

It just shows you were you've already been much like when doing a search, then clicking back to the search menu...the sites you've already clicked on are discolored from the rest.

If you clear your cookies, or close browser (depending on settings) they should all go back to blue.

It's just showing you where you've already been at some point in the recent future. Well, that's the way it is for me and some others I've talked to. This was asked once before and that was the issue then as well.

If it's bothersome to you, try clearing your cookies to see if it resolves it.
