This increases some color contrast in sphinx_rtd_theme to better satisfy web content accessibility guidelines. This is by no means a proper fix, but some quick hacks by an uneducated person. It tries to make minimal changes, though.

This package will be deprecated once sphinx_rtd_theme is improved upstream: readthedocs/sphinx_rtd_theme#971

Currently it is not on PyPI (but could be), because I am hoping sphinx_rtd_theme will be updated before that is necessary. To install, add this to requirements.txt:

https://github.com/AaltoSciComp/sphinx_rtd_theme_ext_color_contrast/archive/master.zip

And then add the extension in conf.py:

extensions = [
   ...
   'sphinx_rtd_theme_ext_color_contrast',
]

Text contrast:

• Increase link text saturation
• Increase literal text saturation
• Increase footer contrast

Update pygments elements for contrast

Admonition colors

• Make the admonition title backgrounds darker.
• These are very long CSS selectors, copied from what the current theme uses.

Make the sidebar background darker
