Modus themes for GNU Emacs (Modus Operandi and Modus Vivendi)

A pair of highly accessible themes that conform with the WCAG AAA standard for colour contrast between background and foreground combinations (a minimum contrast of 7:1---the highest standard of its kind). The Modus themes also strive to empower users with red-green color deficiency: this is achieved through customisation options that replace all relevant instances of green with blue, as well as the overall design of the themes which relies mostly on colours that cover the blue-cyan-magenta side of the spectrum.

The themes are built into GNU Emacs 28 (development target). They are also distributed in several packages formats.

  • modus-operandi is light.
  • modus-vivendi is dark.

For some demo content, check:

Quick setup for the latest version

With use-package:

(use-package modus-themes
  :ensure
  :init
  ;; Add all your customizations prior to loading the themes
  (setq modus-themes-italic-constructs t
        modus-themes-bold-constructs nil
        modus-themes-region '(bg-only no-extend))

  ;; Load the theme files before enabling a theme
  (modus-themes-load-themes)
  :config
  ;; Load the theme of your choice:
  (modus-themes-load-operandi) ;; OR (modus-themes-load-vivendi)
  :bind ("<f5>" . modus-themes-toggle))

Without use-package:

(require 'modus-themes)

;; Add all your customizations prior to loading the themes
(setq modus-themes-italic-constructs t
      modus-themes-bold-constructs nil
      modus-themes-region '(bg-only no-extend))

;; Load the theme files before enabling a theme
(modus-themes-load-themes)

;; Load the theme of your choice:
(modus-themes-load-operandi) ;; OR (modus-themes-load-vivendi)

(define-key global-map (kbd "<f5>") #'modus-themes-toggle)

Note: make sure that you do not customise custom-theme-load-path or custom-theme-directory after the themes' package declaration. That will lead to failures in loading the files. If you must change those variables, do it before the package declaration.

All customisations in short

While you should read the manual for all the details (see next section), here is a snippet with all current customisation options and their possible values. Note that those settings are only for purposes of demonstration:

Further information

Read the Info manual HTML version for how to install, load, enable, and customise the themes. If you are using the latest version of the themes, you already have the manual installed: evaluate (info "(modus-themes) Top") to start reading it.

The themes cover a broad range of packages and are highly customisable.
