I would like as said in the title customize colors of the differents levels in org-mode. I have tried from the customize-group menu then org-face but it looks like I can't change colors there. So, I've to do it manually but what shall I add in my .init.el file ? I've added the package color-theme and tried smth like this :

 (org-level-1 ((t (:foreground "yellow"))))

but I get the follwing error :

Symbol's function definition is void: org-level-1

Unfortunateley I'm quite new to debugging with Emacs...Thanks in advance.

I think your main problem here is actually you do not consider org-level-1 the face but org-level-1 the function (which is not existing as the error message indicates it). You can use something like that to customize in your init file

(custom-theme-set-faces 'user
                        `(org-level-1 ((t (:foreground "yellow")))))

  • my/org-mode-hook (above) didn't work for me, but this one did!

You can customise the colours of different levels with the following steps:

M-x customize <RET>

Then in the search box, enter org level 1 and hit Search button. Then you can see Org level 1 face through Org level 8 face. Expand the nodes you want to modify and set the attributes as you want.

Don't forget to save the result with Save for future session.

You could also make a your own hook for org-mode. That way you could set multiple faces inside the hook and they will all be loaded after org-mode.

(defun my/org-mode-hook ()
  "My `org-mode' hook"
  (set-face-attribute org-level-1 nil :foreground "yellow")
  (set-face-attribute org-level-2 nil :foreground "blue"))  ; just add to the list

(add-hook 'org-mode-hook 'my/org-mode-hook)

  • Consider using an (eval-after-load "org" '(progn . . .)) statement instead of putting this on the org-mode-hook -- the latter potentially gets called a zillion times each Emacs session (e.g., every time an org-mode buffer is created), whereas the former will only do this customization/setup one time. Once its done, its done -- no need to do it more than one time per Emacs session.

    And consider setting the second argument of set-face-attribute to nil (instead of t) so that it applies to all frames (existing frames, and also future new frames). See the doc-string for set-face-attribute.

  • @lawlist I have the second argument set as nil in my own config, though I was mirroring @loukios own choice of t, I'll change it in the anwser.

  • If using a theme, would you need to insure it is loaded before org-mode when using the eval-after-load method? Some themes modify the face attributes of org-mode.

  • There have been a lot of inquiries over the past year about the non-existence of a hook that runs after a theme loads, and the last I checked, there was still no such hook. A user named pkkm has added a hook to load-theme using defadvice: reddit.com/r/emacs/comments/4v7tcj/… (defvar after-load-theme-hook nil "Hook run after a color theme is loaded using 'load-theme'.") (defadvice load-theme (after run-after-load-theme-hook activate) "Run 'after-load-theme-hook'." (run-hooks 'after-load-theme-hook))
