The “Modus themes” is a pair of highly accessible themes for Emacs that conform with the WCAG AAA standard for colour contrast between combinations of designated background and foreground values (a minimum contrast ratio of 7:1).

Modus Operandi is a light theme. Modus Vivendi is dark. The themes are part of Emacs’ master branch, each of them currently tagged with version 0.12.0 , while they are also distributed through various package archives. Consult their Info manual for the specifics (the manual is not yet in Emacs—coming in version 0.13.0 ): https://protesilaos.com/modus-themes.

The present report documents changes that will be made available in version 0.13.0 of the themes, expected at the end of September 2020.

The following is a valid org-mode text that was used to prepare this report. The gist is that even seemingly trivial changes require a lot of work. If, by the way, anyone knows of a more elegant syntax to write those tables, please do contact me: I have little experience with spread sheets, formulas, etc.
