Highlighting is completely unusable?

Hi, I feel like I’m somehow missing something. when i use the highlight tool on a web archive, it renders the text totally unreadable. If you go into preferences, you can ostensibly change the highlight colours but this doesnt seem to actually do anything? And the colour you pick and thats visible in the menu is totally different to the colour in the actual highlight?

For example:

The preferences are just defaults, changing them doesn’t affect any existing highlights or documents. However, in dark mode the colors are adapted. Does this web archive use its own styles or did you disable the option to use dark backgrounds for documents (see Preferences > General > Appearance)?

Aha, use dark backgrounds for documents was in fact the culprit. Thankyou for the pointer, that was making me go a little crazy.
