I occasionally get requests from readers to add a dark mode to my blog - https://simonwillison.net/ - and I'm never sure how much priority I should give those, as someone who almost never chooses to use dark mode.

Dark mode fans: does it really bother you to read white web pages?

This is the privileged majority punching down at minority, not unlike an abled person whining about the existence of accessibility options, or a native-born American complaining about government forms also having a Spanish section after the English section.

There's a reason that extensions like Dark Mode¹ have 10,000,000+ installs while no "Light Mode" extensions can even exist as far as I can tell: more or less the entire internet is already light-mode by default, with no option even provided by webmasters for dark mode for those who want it on a vast majority of websites.

What I can't comprehend is why the people who already have light mode as the default across the entire internet can't be content letting people with a preference for dark mode even exist without aggressively trying to erase the preferences of people who don't feel the exact same way as themselves.

Further, for anyone using OLED panels, which is a non-insignificant portion, black backgrounds reduce power draw and therefore global carbon emissions. Light backgrounds literally accelerate climate change, however marginally.

Yes. I have Dark Reader[1] on by default for all websites and only disable it when it activly breaks a site, or a site has a suitibly dark theme and Dark Reader thus flips things the wrong way.

If a site is borked to the point that Dark Reader can't fix it, I'll use reader mode or just go somewhere else.

Your site looks just fine to me.

Yes. There's a reason that https://darkreader.org/ has 10 million+ installs while no inverse extensions even exist to my knowledge.

The entire web is already light-mode first and much of it, including your site (no offense) offers zero built-in support for the provably massive demand that exists for dark-mode color schemes.

I was going to comment that it’s a bit weird that dark mode is viewed as a new or special option. But someone else already wrote a whole article on that point [1]

No idea why this extremely poor "article" is getting so much attention on HN. There is a time and place for dark mode. For certain demographics, default dark mode may be more suitable than others. And letting the user change it covers all bases.

For example, on my site [1], I default to dark mode (not pure black though) and have settings for changing the theme to: Pure black, Light mode (white), and 2 custom themes which are off white, and a dark blue background.

I picked dark mode as default because my site is directed towards tech people (it's for STEM + Arts and Design) and thought dark mode works well for that theme.

That article needs way more meat.

I’d recommend this classic for a read: https://graphicdesign.stackexchange.com/questions/15142/whic...

Tl;dr dark text on a light background is usually easiest to read. Note in dark mode, you often see font bolded to compensate for the readability drop.

Almost ever major website dosent use dark backgrounds for text for a reason.

I personally like a dark mode UI (menu bars, dock, and so on), so it’s less distracting, but light mode for content.

I learned a bit about that historical context from this long-form video: https://www.youtube.com/watch?v=jKJFC5UfmoY

Install Darkreader, enable Light mode

https://darkreader.org/

I think most users are capable of that :)

I might be too naïve but

  > For example, where is the color palette defined?
There's literally an option for "auto", "light", and "dark" on each page. If changing the default value from "light" to "auto" is not a single variable change then honestly I believe there are bigger issues. There's a master template in their code where they set the default option...

I'm saying it's silly to have an "auto" option and not making it the default. I'm not sure how this is anything but laughable. But again, if I'm being naïve here, I'm happy to hear the reasoning. If I'm naïve then it means I'm in need of being informed.

  > That wouldn't be helpful anywhere outside of Wikipedia.
Well that specific complaint was about Wikipedia. I'll stand by that Wikipedia should change from a default value of "light" to "auto". Unless you have a compelling argument against this?

There are other websites that have a toggle and don't read the browser or os theme. That might require an additional few lines to do so but let's also not pretend that's hard.

If your website doesn't have both a light and dark theme, that's out of scope of my complaint. My complaint for those is: if using a template site that you didn't create, use one with this feature, there's millions. Else (you didn't use a template), please add this feature, the fact that these fights exist is irrefutable evidence that people value both options. It's evidence that there's very strong preferences and the work isn't useless (though may be hard to measure its effectiveness)

  > Maybe if you link to the Wikipedia page you're talking about that would help.
You can visit any article on Wikipedia and you will see the options for this on the right side.

I have older eyes. I'm sure someday in the next few years I will have cataract surgery.

Light mode is lower contrast for me, and is more difficult to read text, especially at the end of the day.

Dark mode is a relief, and much easier to read for me.

I miss it in the situations when it is not available, like PDFs with small grey text on a white background, more so on a small screen like a phone.

Some people think dark vs light is opinion, but for some it is not.

- dark mode may present some advantages for some low-vision users

- in users with normal vision, light mode leads to better performance most of the time.

- applications meant for long-form reading (such as book readers, magazines, and even news sites) should offer a dark-mode feature
