Here is an example of how to color search results based on tags.
(the following text would be placed in your ~/.emacs file):
- (setq notmuch-search-line-faces '((\"delete\" . (:foreground \"red\"
+ (setq notmuch-search-line-faces '((\"deleted\" . (:foreground \"red\"
:background \"blue\"))
(\"unread\" . (:foreground \"green\"))))
The attributes defined for matching tags are merged, with later
-attributes overriding earlier. A message having both \"delete\"
+attributes overriding earlier. A message having both \"deleted\"
and \"unread\" tags with the above settings would have a green
foreground and blue background."
:type '(alist :key-type (string) :value-type (custom-face-edit))
