FinderColor is a an extremely simple interface to the Finder label colors in Mac OS X. It uses Apple Events via the rb-appscript bridge to allow the getting and setting of colors without locking up the Finder using AppleScript. FinderColor can get and set labels by index or by color names (as symbols, e.g. :none, :orange, :red).
