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.

Being unable to stand both white text on black and black text on white, I have found setting the foreground to black and the background to gray60 (in emacs and the terminal) is what allows me to look at a screen for hours without pain.

(Interestingly enough, I too have an astigmatism in one eye, but I don't know if that's the sole cause of my discomfort.)

that's a bit disappointing, seeing as this format is by far my favourite because of it being very simple and aesthetically pleasing.

any suggestions? my intuitive response to this would be black on brightly hued navy blue, but i worry that is also low-contrast, which also causes issues.

can't please everyone!
