Growlers

Growlers is a nice collection that includes over 70 high quality purple replacement icons that will give a colorful look to your Mac.

Every volume (disk), application, file, and folder on your Mac is represented by an icon. Volume icons tend to look like the item that they represent, for example, your hard disk looks like a hard drive, CDs and DVDs look like discs, and removable drives look like removable drives.

Elegant Icon Set allows you to give an original touch to your desktop no matter the file types or applications you choose to associate.
