This theme is just fork from sexy-monochrome-theme which is based on the Xavier Noria monochrome-theme. And impressed by "Monochrome color scheme for Vim"

I think colour make me confused when you start hacking. However, I would recommend using colors when you are learning new language.

throw this file into ~/.emacs.d and_

     (add-to-list 'custom-theme-load-path
                  "~/.emacs.d/YOUR_FOLDER_WITH_THEME/")

and

     M-x load-theme RET simple-monochrome RET

then put in your init file

    (load-theme 'simple-monochrome)

Works with Emacs >= 24.
