Conditional ColorSchemes allows you to define color schemes per file, folder, extension, and directory structure via RegEx patterns. You can define as many RegEx patterns as you need, each with a different color scheme.
This plugin started as a response to this StackOverflow question. I figured it might be generally useful for you guys, so I added some features in addition to the initial requirements and submitted it to PackageControl.
Examples:
Folders & Directory Structures
