Chroma

Chroma is an OS X Dashboard utility for converting colors between HSV, RGB, and HEX formats, including 256 integer, percentage, and floating point variations. Favorites can be saved to the swatch library, and exported or imported via the system clipboard.

IMPORTANT: Version 4.0 includes an all new library system, support for multiple types of data (256 integer, percentage, and floating point values), updated copy/paste, and many other updates.

To transition your old library, navigate to the location you saved it originally and copy the contents of the text file to your system clipboard. In the Chroma widget settings (click the "i" icon in the upper right hand corner), select "import" and choose how you want to treat the incoming data. Values will be automatically converted into the new floating point format and saved in the internal library. Data can be exported and traded between computers using the same method. While this may not be ideal for syncing a library across systems, it should be much more robust, avoiding the 4096bit limit seen on some macs while using the command line to save the full library to a flat file. Bugs could still be present, however, so I look forward to any feedback you might have!
