GNOME Brave Folders is for everyone who, like me, like the Gnome 3 default icon theme - apart from the folders. This theme replaces the folder icons with sleek blue ones (brave) from GNOME-colors, while keeping everything else as it were.
Remember, this icon theme depends on the "gnome" theme.
DISCLAIMER: I did not make these icons. This is simply a repackaging of select icons from the GNOME-colors icon theme by perfectska04 (http://gnome-look.org/content/show.php/GNOME-colors?content=82562).
