Folder Style

This utility adds variety to folder icons so that you can spot the one you need at a glance. The simple Folder Style interface makes it easy to change the look of an individual folder, although changing a large group takes a while. The program comes with a large collection of icons, including some for the Mac, or you can use your own images. Folder Style doesn't classify icons, which makes it difficult to view large collections. The program also doesn't let you automate icon changes based, for example, on when you last accessed the folder or file type. However, if all you want to do is customize folder icons, Folder Style may suffice.
