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?
