I understand the concerns, especially how it interacts with some themes - I'll certainly bring examples up with the team.

The nature of this change was mainly just updating the CSS for the modern MediaWiki standard - implementing a preference would be a lot more work. We'll look into tweaking the colours to work better across different situations. (And more examples are welcome, particularly via Special:Contact.)
