  # Modus themes for GNU Emacs

  IMAGES HERE: <https://protesilaos.com/emacs/modus-themes-pictures>.

  Highly accessible themes, conforming with the highest standard for
  colour contrast between background and foreground values (WCAG AAA).
  They also are optimised for users with red-green colour deficiency.

  The themes are very customisable and provide support for a very wide
  range of packages.  Their manual is detailed so that new users can get
  started, while it also provides custom code for all sorts of more
  advanced customisations.

5.0.0 on 2025-11-01
═══════════════════

  This is a major release. There are some small breaking changes. The
  big new feature is that Modus can be used as the basis for other theme
  projects. Two of my other theme packages, the `ef-themes' and the
  `standard-themes' are already done in this way: their next major
  versions will formalise what I have been developing for a while now
  (though the `doric-themes' will remain their own thing for the time
  being).


Build on top of Modus
─────────────────────

  This is of immediate interest to package developers or advanced users.
  It changes nothing for existing users of the Modus themes. Please
  refer to the manual on the matter and feel welcome to contact me if
  you have any questions—I am happy to help.

  Why build on top of Modus? To benefit from (i) the wide face coverage
  and extensive detail-oriented testing, (ii) the use of palette
  mappings, (iii) the palette preview done with
  `modus-themes-list-colors' or related, (iv) the inclusion of the
  derivative theme in the workings of all Modus commands that load a
  theme, like `modus-themes-rotate' and `modus-themes-select' (see the
  new minor mode `modus-themes-include-derivatives-mode').

  Derivative themes can be as simple as a few extra colours on top of,
  say, `modus-operandi'. They can also be more involved, with new
  palette mappings and custom faces that use them. Such themes can
  define commands which load only their own themes (see
  `modus-themes-define-derivative-command') and they can even take over
  the Modus themes completely, in terms of becoming the only ones that
  are exposed to the commands that load a theme, like
  `modus-themes-rotate' and `modus-themes-select'.

  Thanks to Suleyman Boyar for fixing an intermediate omission with an
  earlier version of the code that derives a theme. I did eventually
  change the whole approach to use a function instead of a macro, but
  Suleyman's contribution was still useful at the time. This was done in
  pull request 156:
  <https://github.com/protesilaos/modus-themes/pull/156>.  The change is
  small, meaning that Suleyman does not need to assign copyright to the
  Free Software Foundation.


Colours can be copied from the palette preview buffer
─────────────────────────────────────────────────────

  The commands `modus-themes-list-colors' and
  `modus-themes-list-colors-current' display the given theme's palette
  in a tabulated listing. Each line visualises the colour it
  references. From that buffer it is now possible to call the following
  commands (bound to the `modus-themes-preview-mode-map'):
