I think the styling in the Apex theme is actually a bit better. (Screenshots below are from <https://gerrit.wikimedia.org/r/284902>.)

Warnings are even worse, they are set in the same font and color as any random label and only highlighted with a small icon.

The styles here were created by myself when implementing this feature (which we needed urgently for OOjs UI HTMLForm: T106947) and I probably spent about 30 seconds thinking about them. We should rethink them ;)
We might draw some inspiration from the success/warning/error message boxes in MediaWiki, see {T127405}.
