In The Dark Mode
One of the many spoof posts that appeared on arXiv on April Fool’s Day was one about Dark Mode:
You will note that In The Dark has been using a kind of Dark Mode for over 13 years. The style is actually called Black Letterhead and I picked from among the available themes when I first started blogging because it seemed to me to match the title. This theme has actually been “retired” but still seems to work and I don’t feel any urge to change it.
A few people over the years have complained that the white text on black background is quite hard to read, but only a few. If you don’t like it you can easily change the colour via your web browser settings, of course. I think Dark Mode works better with a sans serif font, by the way.
I actually find it easier to read than black on white, actually, consistent with the fact that I find a chalkboard easier to read than a whiteboard which is why I have one in my study:
Although the paper was intended to be a joke, it does make some interesting points and is well worth reading!

When I read this blog on a mobile phone, I’m afraid it defaults to black text on a black background. Is this something you have any control over? I do prefer the white text on black.

That’s strange; when I read it on my phone it reverts to black text on a white background. My phone is Android so I’m guessing yours is an iPhone, although it may be more to do with the browser.

Doh. Black text on a white background is what I meant. I have an android phone too. But if even you, the blog owner, can’t persuade it to look as desired, with white text on a black background, I guess there’s no hope.

I think WordPress has a fixed format for ‘mobile-friendly’ access which is a boring one. I think some people would argue than black-on-black would be an improvement!

Printed with ink made from dark matter, I presume.

Did you hear the one about the bloke who went to A&E because he swallowed a load of invisible ink?
He’s still waiting to be seen.
