How do I change the comment color in emacs lua-mode.el?

Question

The title is pretty self explanatory.

I would like to change the comment colour from black to green in lua-mode.

I've tried putting this into .emacs (set-face-foreground 'font-lock-string-face "red")

But it didn't work. Any ideas?

Answer 1

If you put the cursor in the comment, and type M-x customize-face RET, it will offer to customize the correct face automatically (in this case font-lock-comment-face as Rupert mentioned). This gives you a nice way to play around with different changes to the face (to get exactly the right color etc.) and then save it to your .emacs. This is the easiest way to find out any face that you want to change.

Answer 2

At least on my version of Emacs, if I call describe-face on a bit of a comment in a Lua file, I get font-lock-comment-face, rather than font-lock-string-face. Have you changed the wrong variable?

Answer 3

I've solved it.

Uninstalled emacs 23 apt-get remove emacs

Followed the instructions from: https://launchpad.net/~cassou/+archive/emacs Installed emacs-starter-kit: https://github.com/technomancy/emacs-starter-kit

Installed lua-mode with M-x package-install RET lua-mode

Restarted, and loaded a lua file. Now both single and multi-line comments have the same comment color and I can change it by setting font-lock-comment-face color which by default is brickred, to darkgreen according to Ivan's answer above.
