About

Zenburn for Emacs is a direct port of the popular Zenburn theme for vim, developed by Jani Nurminen. It's my personal belief (and that of its many users I presume) that it's one of the best low contrast color themes out there and that it is exceptionally easy on the eyes.

This theme uses the "new" (it used to be new several years ago when I created this package) built-in theming support available starting with Emacs 24.1.

Installation

Manual

Download zenburn-theme.el to the directory ~/.emacs.d/themes/. Add this to your .emacs (or init.el):

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

Now you can load the theme with the interactive function load-theme like this:

M-x load-theme RET zenburn

Package.el

Zenburn is available in both MELPA Stable and MELPA.

You can install zenburn with the following command:

M-x package-install zenburn-theme

To load it automatically on Emacs startup add this to your init file:

(load-theme 'zenburn t)

Emacs Prelude

Zenburn for Emacs is already bundled into Emacs Prelude. If you're a Prelude user - you're probably already using Zenburn, since it's Prelude's default color theme. You can load Zenburn at any time by M-x load-theme zenburn.

Debian and Ubuntu

Users of Debian 9 or later or Ubuntu 16.10 or later may simply apt-get install elpa-zenburn-theme.

Customization

Custom colors

If you'd like to tweak the theme by changing just a few colors, you can do so by defining new values in the zenburn-override-colors-alist variable before loading the theme.

For example, to customize just the lighter background colors, you could add to your init file:

(setq zenburn-override-colors-alist
      '(("zenburn-bg+05" . "#282828")
        ("zenburn-bg+1"  . "#2F2F2F")
        ("zenburn-bg+2"  . "#3F3F3F")
        ("zenburn-bg+3"  . "#4F4F4F")))
(load-theme 'zenburn t)

To see the full list of color names you can override, consult the zenburn-theme.el source file.

Scaled headings

The theme supports scaling the font size for some headings and titles as well as using a variable-pitch font for those. To enable this, use the following settings:

;; use variable-pitch fonts for some headings and titles
(setq zenburn-use-variable-pitch t)

;; scale headings in org-mode
(setq zenburn-scale-org-headlines t)

;; scale headings in outline-mode
(setq zenburn-scale-outline-headlines t)

The screenshot above shows the default setting with no scaled or variable-pitch fonts. With scaled headings and variable-pitch fonts it looks like this:

Ugly colors in the terminal Emacs version

If your Emacs looks considerably uglier in a terminal (compared to the GUI version) try adding this to your .bashrc or .zshrc:

export TERM=xterm-256color

Source the .bashrc (or .zshrc) file and start Emacs again.
