Speaking from my own disability I'd say I'd much prefer if people used white on dark text over any use of light background. But this is because my own issue is with photosensitivity which affects a large number of low vision users.

In fact I often create white on black content because it is easy for me to author and read. I also have significant color blindness and am totally unsure which color combinations are hard for others to read, may not show up on a projector, may be a faux pas or may be gaurish.

And this is the profound difficulty of creating accessible content. What is accessible for one is often not accessible for others with a different disability. Simply saying don't do this or don't do that has long ceased to be considered a good method of creating accessible content. This has been abandoned in favor of using a broad suite of tools to validate content meets a wide array of accessibility needs.

Edit: I have never looked into whether such a tool exists for common slide presentation apps.

Maybe you find this browser extension useful: https://darkreader.org/
Thanks. On desktop I use Windows High Contrast Black which is excellent. Firefox does a pretty good job of modifying web content to follow that theme. The main issue I haven't solved is mobile browsing. Most mobile browsers don't allow extensions and the OSes don't have anything like Windows High Contrast Mode except invent but that's never been a great solution for me.
This extension works on mobile firefox
Dark Reader in dark mode with the contrast turned down has saved me from soo many migraines <3
If both options cause problems, you should pick the one with the best workaround. Sunglasses can reduce brightness, but increasing brightness is much more difficult, so dark text on light background is correct.
No, sunglasses aren't going to fix contrast sensitivity due to photophobia. As a low vision person putting on sunglasses inside just means I can't see anything.
It’s possible to get polarised lenses that have about 50% transmission which is quite comfortable for computer work. At least for me they are anyway.
