The extras-gnome-colors package includes application themes and recommended icons that may not be included with the GNOME-Colors icon set, as they will replace existing files.

To install the extras, either copy the desired color-scheme's "usr" folder to your filesystem as administrator "sudo nautilus /" and click "Merge All" when asked, or use one of the available Ubuntu scripts.

In Ubuntu, simply double click the desired color-scheme script, and then select "Run in terminal". If the script doesn't run, try right-clicking it, and check "Allow executing file as a program" in its permission properties.

The extras include matching icons or application themes for Firefox, Thunderbird, Inkscape, Comix, Liferea, Exaile, etc...

BE SURE TO BACKUP PREVIOUS ICONS AT YOUR DISCRETION IF YOU INSTALL THE 'EXTRAS'.
