That wasn't part of your original problem statement.  Put this in a 
"test.el" file:

(load-theme 'modus-vivendi t)
(global-display-fill-column-indicator-mode)
(set-face-attribute 'fill-column-indicator nil :background "green" :foreground 
"green" :height 0.3)

and start Emacs as above (emacs -Q -l test.el).  If the bar is not thick 
enough, you can make the :height value larger.

You're welcome.
