With the following in my .emacs I get narrow margins in text-mode buffers:

(defun my-set-margins ()
  "Set margins in current buffer."
  (setq left-margin-width 30)
  (setq right-margin-width 30))

(add-hook 'text-mode-hook 'my-set-margins)

How can I change the color of the lines that appear to delimit these margins so that it's the same as my background color and not black like they are now?

Current margins with black lines


I know more now and this is my question:

How do I add a hook to turn of the fringes in text-mode?


This worked:

(set-face-attribute 'fringe nil :background "#2E2920" :foreground "#2E2920")

#2E2920 being my background color.
