Thank you Professor Kitchin. Would something like follows would work?
#+BEGIN_SRC emacs-lisp :results silent
(add-hook 'org-mode-hook (lambda () (font-lock-add-keywords
                                     nil
                                     '(("^-\\{5,\\}"  0 '(:foreground "red" :weight bold))))))
#+END_SRC

you can add a rule like this in an org-mode hook:

#+BEGIN_SRC emacs-lisp :results silent
(font-lock-add-keywords
 nil
 '(("^-\\{5,\\}"  0 '(:foreground "red" :weight bold))))
#+END_SRC

that will make a line starting with at least 5 - be red and bold in color.

You could use hi-lock-mode to define your own colouring for such
lines.  But I'm sure those that under font-locking better might be able
to add appropriate rules for this horizontal line construct.
