Math generated with sphinx.ext.imgmath is not readable in dark mode

[tdegeus]

Consider a very simple document:

Foo
===

.. math::

    a = b

configured as

project = "Foo"
copyright = "MIT"
author = "Bar"
extensions = ["sphinx.ext.imgmath"]
exclude_patterns = ["_build", "Thumbs.db", ".DS_Store"]
html_theme = "furo"

Then the white-background version is perfectly readable:

but the equation is completely unreadable in dark mode

It would be great if there would be a way to invert the colours. Or at least render black as white in the equation.

Without a screenshot, a hosted webpage that I can look at and/or the source code used to build that webpage, there's no way for me to figure out what's happening. :)

Sorry, you are completely right. Edited.

Ah right! Using sphinx.ext.mathjax instead will work -- I don't think I've ever seen someone use sphinx.ext.imgmath "in the wild". 😅

If someone really wants to use imgmath for some reason, lemme know and I'd be happy to explore implementing this -- I've never actually installed latex on my MacBook, to figure out how to get imgmath working correctly. :)

I did not really think about the difference. I guess it was some hit I got on the internet a million years ago that I'm still using... Thanks!
