Okay -- I've made a little progress. I now have this:
;; Custom colors
(defface my-group-face-1
'((t (:foreground "Red" :bold t))) "First group face")
(defface my-group-face-2
'((t (:foreground "Green" :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")
;; Apply custom colors dependent on regex matching
;; Need to limit to certain groups
(defun pja-gnus-git-color ()
(interactive)
(highlight-regexp "^-.*" 'my-group-face-1)
(highlight-regexp "^+.*" 'my-group-face-2))
(add-hook 'gnus-article-display-hook 'pja-gnus-git-color)
The first part defines new colors. The second part applies them using
my defined function which is called with gnus-article-display-hook.
This all works like I want it to...sort of. If I go to a message in my
Git commit group I see lines that start with "-" as red and "+" as
green. But, it only works on the first message I view in that group.
If I hit "n" the next message doesn't have the highlighting. If I hit
"P" to go back to where I just was, the highlighting isn't there now.
If I exit the group "q" and go back in the first message I view will
display the custom colors.
What am I missing?
Thanks,
Peter
