Hello Linux Geeksters. In this short article I will show you how to install easily color the folder icons on your Kubuntu 14.04 Trusty Tahr system, using Dolphin as the default file manager.
All you have to do is download the Dolphin Folder Color app from kde-apps.org:
$ cd ~
$ wget kde-apps.org/CONTENT/content-files/164008-dolphin-folder-color.tar.gz
$ tar -xzvf 164008-dolphin-folder-color.tar.gz
$ cd dolphin-folder-color && rm 164008-dolphin-folder-color.tar.gz
Optional, to remove Dolphin Folder Color, do:
$ rm -r ~/dolphin-folder-color
Next, log out and log back in. Now, when you right-click a folder via Dolphin, you will have a Color Chart button, which enables you to select the color you want your folder icon to have.
If your Ubuntu/Linux Mint system use Nautilus/Files or Nemo as file managers, and want to change the color of your folder icons, follow the instructions in THIS article.
