Highlighting in the group buffer is controlled by the
gnus-group-highlight variable. This is an alist with elements
that look like
(form . face). If form evaluates to
nil, the face will be used on the line.
Here’s an example value for this variable that might look nice if the background is dark:
(cond (window-system (setq custom-background-mode 'light) (defface my-group-face-1 '((t (:foreground "Red" :bold t))) "First group face") (defface my-group-face-2 '((t (:foreground "DarkSeaGreen4" :bold t))) "Second group face") (defface my-group-face-3 '((t (:foreground "Green4" :bold t))) "Third group face") (defface my-group-face-4 '((t (:foreground "SteelBlue" :bold t))) "Fourth group face") (defface my-group-face-5 '((t (:foreground "Blue" :bold t))) "Fifth group face"))) (setq gnus-group-highlight '(((> unread 200) . my-group-face-1) ((and (< level 3) (zerop unread)) . my-group-face-2) ((< level 3) . my-group-face-3) ((zerop unread) . my-group-face-4) (t . my-group-face-5)))

Variables that are dynamically bound when the forms are evaluated include:
The group name.
The number of unread articles in the group.
The select method.
Whether the group is a mail group.
The level of the group.
The score of the group.
The number of ticked articles in the group.
The total number of articles in the group. Or rather, max-number minus min-number plus one.
When using the topic minor mode, this variable is bound to the current topic being inserted.
When the forms are
evaled, point is at the beginning of the line
of the group in question, so you can use many of the normal Gnus
functions for snarfing info on the group.
gnus-group-update-hook is called when a group line is changed.
It will not be called when
