I recently installed Cinnamon and noticed that as I change the GTK, Cinnamon and icon themes, the panel icons remained the same. How can I change them to match my icon themes?
Note that the battery icon is not part of my icon theme, it was like that from the start.
I suppose you have Cinnamon installed and running in your computer.
Cinnamon has a Website with themes, extensions and applets. Here is the link for themes:
http://cinnamon-spices.linuxmint.com/themes
You have to download the theme you like and uncompress it in /home/your_user/.themes
If you do not have the .themes folder, you can create it. So you must finally have, for the Minty theme for example, the next path: /home/your_user/.themes/Minty
The Minty folder is the uncompressed theme. Into that folder there is another folder called cinnamon (check this for all the themes you want to install).
Then you will be able to select the theme you installed using Cinnamon Settings (program included with Cinnamon).
The GTK themes are needed for the windows. You can get them from Gnome-look.org, for example. These themes must be installed into the same path (/home/your_user/.themes). Then you can choose the GTK theme in Cinnamon using Cinnamon Settings too. You can't use Gnome-Shell themes with Cinnamon. You have to use Cinnamon themes.
Sorry for my poor english.

I've found out that the applets use different icons than what comes in an icon theme. It says what the icon is in it's applet.js file. It's easy to find it, open the file and search for "icon-name" or "icon_name" and you should be able to find it. These usually have "symbolic" in their name. These are also the same icons that are used in Gnome-Shell's panel
