I'd like to change the color of Next to Red and Started to brown. At the
moment, todo/ next and started all showing as red.

Here is my .emacs snippet.

(setq org-todo-keywords
            '((sequence "TODO(t)" "Next(n)" "Started(s)" "|" "DONE(d!)")
              (sequence "|" "CANCELED(c)")))

(setq org-todo-keyword-faces
           '(("CANCELED" . (:foreground "blue" :weight bold))))
