save the file in a desired location, for example "$HOME/.emacs.d/lisp/lib/color-theme/sph.el"
somewhere in your emacs config, for example "$HOME/.emacs", add the following
(add-to-list (quote load-path) "~/.emacs.d/lisp/lib/color-theme") (load-library "sph") (setq frame-background-mode (quote dark)) (color-theme-sph-dark)
in this case emacs should import the library and use the dark theme the next time it starts
the themes can also be manually selected using "M-x"
make sure that appropriate background color is selected in the terminal
there is also a light version which needs a little tweaking
