Esmond is a dark color scheme for emacs
Download esmond-theme.el
to the directory ~/.emacs.d/themes/
and add this
to your .emacs
or init.el
(add-to-list 'custom-theme-load-path "~/.emacs.d/themes")
If you want to load it by default you can add this line to your init file
(load-theme 'esmond)
Esmond is avaliable on MELPA, you can install it with
M-x package-install esmond-theme
If you cannot find the package try M-x package-refresh-contents
If your color scheme does not look the same as in the screenshot it might be due do rainbow-delimiters mode I am using. If you want to get the same coloring for brackets and braces you can install that package. And set the max face count to 1 with
(setq rainbow-delimiters-max-face-count 1)
