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\"
- :background \"blue\"))
- (\"unread\" . '(:foreground \"green\"))))
+ (setq notmuch-search-line-faces '((\"delete\" . (: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\"
