Is it possible to change the Finder sidebar icons

I know you can change the icons of files, folders, etc, but in the sidebar folders appear the same. Is it possible to give them a custom icon for the sidebar like the Music, Photo's, Movies, etc folders have?

CandyBar should do the trick for you.

If you want to use the default Mavericks OS X Finder Icons, go to System/Library/CoreServices/CoreTypes.bundle (right-click > Show Package contents)/Contents/Resources.

1. Get Info on the folder in finder sidebar.
2. Drag the .icns file (e.g. ToolbarDownloadsFolderIcons.icns on to the small icon in Get Info window to the left of Downloads.
