I would have thought so to but looking at the white background digrams on the dark pages was a horrible experience. It pretty much defeated the entire purpose of having a dark mode as there was these bright white diagrams shining in my eyes.

Which is better you can compare

Here's before dark mode

Here's leaving the backgrounds to the diagrams white

And here's the hue rotated solution

The ideal solution would be to make all the diagrams twice but that's a ton of work if your site has lots of diagrams. Of course it's all an opinion. I don't have time to redo all the diagrams or go make them CSS styled indivdually so this is the solution I chose for now.

Yeah, the hue rotation is really nice. Do you have a real example where it doesn't work?

that can be like a lighthouse in a dark night. flux can help of course, but if you are serious about supporting dark mode then you should eliminate as much white space as managable.

I think he means if you're serious about dark mode then design two graphs one light, one dark. Solving "how do I turn a well designed light mode image into a dark mode image" is an AI task that would be a nice research paper, not something a designer can hack together with a bunch of if-then rules.
