I just noticed that I have THREE colors in my Mailbox Inbox list
(1) Black: Messages before 10:49 AM today.
(2) Blue: Three messages (11:03 AM, 11:11 AM, and 11:19 AM) today
(3) Ugly orangish-brown: Messages since March 13, 2013.
There is overlap. I can't figure-out exactly how they are broken-up.
FINALLY! I don't know how it happened, but the list is now in blue since 11:03 AM, today. Before then, the colors are all jumbled-up.
