Don't. Ever. Publish. Stuff. That. ONLY. Supports. Dark. Mode.

I mean, I know a LOT of people love dark mode, and given the benefits that darkening interfaces provides... I get it.

But there are some people (like me) who may be visually impaired. Astigmatism, for example, can make reading text that is white on dark a real PITA. An effect known as "halation" occurs, where each letter behaves as if it were a flashlight, gaining its own halo of light and making all text read more blurry than normal.

No matter how good your glasses are, astigmatism still causes you to see a little blurry—it's something you get used to. But this damn effect makes all the text read as if you don't have your glasses on, or even worse, leading to much more tired eyes or even pain.

For everyone's sake, if you really care about accessibility, respect user preferences. If you want a dark interface by default, offer a light version if the user specifies it (in web design, this would be
prefers-color-scheme: light). The same goes for light interfaces.

@naipotato Also, PLEASE do not have prefers-color-scheme be your only method of light/dark mode selection.

I find that for my astigmatism that a slightly purple/blue dark mode is perfectly readable and easier on the eyes than light mode, but a slightly yellow dark mode (thankfully rare) is basically equivalent to taking my glasses off.

I once found that a reference site I needed to use only used prefers-color-scheme, and that they used a particularly bad dark mode. I had to change my system settings in order to use that website. (Luckily, they’ve since fixed both issues, adding a toggle and making dark mode more purple)
