Hear, hear.

Back when I attempted to be an edgy college guy, I carried my Gentoo with green foreground on a black background. EVERYWHERE. My pcmanfm (yes, I was one of those) looked glorious in true matrix style (and I did have a matrix screensaver). I did it because it was "cool", not because I felt that dark mode was better.

Then when I changed to MacOS, since there wasn't native dark mode, I don't think I ever _thought_ of even changing it. Things just looked great and I had no complaints.

And, as I've aged, dark mode started to actually hurt my eyes.

There's a special kind of dark mode which I can never put my finger on and literally makes my head hurt. I can feel my light adjusting itself to the change and the blurriness settling in. Every letter seems to transfer some of its weight onto neighboring letters, even those in a previous paragraph with quite a large vertical gap! I don't see the letters overlap but it's like my mind is telling me that they ARE overlapping. It's bizarre but it's the best description I can give: my brain is convinced they overlap, even though my eyes disagree.

I can never focus on those websites and have to quit immediately. Usually pitch black is bad, but I've seen some websites make it work. I once read it has to do with astigmatism and ever since then I've paroted that, but I have friends with astigmatism who scoff at my white/light mode.

Examples (most of them from random googling):

- This is terrible. The green makes my head hurt and it's very hard to focus on it. https://anilkody.framer.website/?ref=darkmodedesign

- This is ok. https://www.danielsantos.co/

- Our company's website is fine https://www.cron.studio/

- Also ok https://superset.sh/

- Unbearable: https://www.omnius.so/web-development

I'm a guy who loves to have the maximum brightness, and incredibly bright lights. I'm not kidding: if I work against a black wall I'll go crazy. Back at my parent's place I pointed 4 different strong ceiling lights at the place where I used to have the computer to make sure it was LIT.

It sort of sucks because there's an increasing amount of dark-mode only websites and I've had to occasionally apply custom styles to them just to browse...

This is probably astigmatic halation. For me it looks something like this: https://www.threads.com/@mrmedina/post/CuciL0Uvam9

If a product/service/site is dark-mode only, I can't/won't use it.

Only some dark mode does this to me, and only on some screens. I find "light mode" bearable, but anything else cute like custom fonts or whatever and I am seeing 33 as 88 and 100 as loo.

I have schwas in my vision, like swishy halos around light sources. At one point I counted 12 distinct mirrored images. Driving was awful.

Reading my 4k screen was impossible, gave it to my wife and switched to a 2k HDR at 175%.

I still have swishes but only 1.5-2 and much dimmer. It used to be impossible to read the clock on my stove at night because it would just be a green smear!

Ooh do me! My site is purposely annoyingly retro!

Your website is ok. The blue-on-black text in the footer is very blurry but that's also part of the CRT-filter design.

Since most of the actual text is not "white on dark", but "dark on blue", it's very readable.

The blue version is fine. The best of all 3 by a large margin

The amber version signals me that I should stop looking at it eventually, though I hang on for a while

The green version hurts my eyes. I want to leave as soon as possible

I think the green is brighter to me than the amber and, on top of that, the black text on green background somehow also gets hard to read.

So you definitely made the right choice going with that default!

It's funny how over saturated that green is on my phone's OLED screen vs my desktop's LCD. The green is retro on my desktop my very not retro on my phone. It is supposed to be a subdued retro green not the overly saturated color that mobile makes it out to be!

The blue comes across truest to my vision on both LCD and OLED displays.

Thanks for giving it a look! :)
