Xresources Color Scheme
http://github.com/solarized/xresources
Use of color schemes with X Windows is heavily dependent upon one's local configuration. Please see the fine Arch Linux wiki for guidance on the use of .Xresources and related files.
Further information on the .Xresources file and its place in the X Window System can of course be found on Wikipedia.
