I just published version 0.3.0 of the Modus themes. These are my highly-accessible themes for GNU Emacs. They conform with the WCAG AAA standard for colour contrast accessibility (a minimum contrast ratio of 7:1 between the foreground and background values). You can find the packages on MELPA:

• modus-operandi-theme (light)
• modus-vivendi-theme (dark)

Below is the complete log of all the relevant changes since 0.2.0 (2019-12-18).

• Add support for the following packages:
  • apt-sources-list
  • calfw
  • counsel-css
  • counsel-notmuch
  • counsel-org-capture-string
  • cov
  • disk-usage
  • evil-visual-mark-mode
  • geiser
  • keycast
  • org-journal
  • org-noter
  • paren-face
  • powerline
  • vc
  • xah-elisp-mode
• Explicitly style the following packages (these were already covered, in terms of the colours they used, but are now targeted directly):
  • calendar
  • counsel
  • cursor
  • package (M-x list-packages)
• Minor tweaks to face groups:
  • dired
  • compile
• Fixes and refinements:
  • Documentation strings will now inherit the option for slanted constructs (off by default – see the README about all the user options).
  • Comment delimiters have the same styles as the body of the comment to avoid inconsistencies when the option for slanted constructs is enabled.
  • The line number that is displayed in the compile log is now correctly styled.
  • Removed duplicate entries for ivy-remote and added ivy-separator.
  • Ensure that the minibuffer prompt is always above the minimum contrast ratio of 7:1, by using a more appropriate shade of cyan.
  • Properly reference a couple of variables in Modus Vivendi.
• Internal adjustments:
  • Decouple the core dired faces from those of external packages.
  • Same for org and org-recur.
• Minor documentation updates.
