On a standard PC keybord without modifications, in Emacs parlance DEL is
the key with a left arrow above your RET key, not the one labelled DELETE.

It means they are marked as read but not read.

,---- (info "(Gnus) Read Articles")
| `O'
|      Articles that were marked as read in previous sessions and are now
|      "old" (`gnus-ancient-mark').

The dark blue face is gnus-summary-normal-ancient, « Face used for

That is used by Gnus when it tries to hook articles to a thread based on
something other than In-Reply-To: on References: headers.
