Arbitrary font faces can be specified for given thread tags. By
default, no coloring is applied. To specify coloring, place something
like this in your .emacs:
(setq notmuch-search-line-faces '(("delete" . (:foreground "red"))
("unread" . (:foreground "green"))))
Order matters: line faces listed first will take precedence (in the
example above, a thread tagged both "delete" and "unread" will be
colored red, since the "delete" face is listed before the "unread").
