There's an #EEE text on #FFF at the bottom of the post.

The title is also showing up as #EEE on #FFF for me, but the inspector view is showing a bunch of other "computed" colour values in the CSS.

And the title too.

The page has a @media (prefers-color-scheme: dark) style that causes this, so those in light mode are unaffected.

Oh - I'm in light mode and all the text on the page is #111111 with a #ffffff background. Switched to dark mode and now I see what you're saying - indeed that's not great.

There seems to be a bug in this blog's stylesheet where the headings are significantly lower contrast if the browser renders prefers-color-scheme as dark instead of light.

I had my browser/OS in light mode, so the contrast was excellent, but I tried dark mode just to see what would happen, and it was... not excellent.

Thank you! This is my site, and your comment helped me fix it.

Yes, I found the main body perfectly readable, but the lighter grey on white could be a problem for some. I'd use something like #777 or darker here.

One problem is that IPS panels only have a contrast ratio of 1:1000 at best, meaning that #000000 black is already gray.

I often have trouble with grey fonts. Thanks to dyslexia, the letters look all fuzzy.

This particular website isn't bad. If the grey were just a bit lighter, it would be.
