SF is a lot more blue than it used to be. (I also noticed this on Ask Ubuntu, so it seems to not be just us.)

Numerous visual elements that were gray, yellow or red, such as tags and user cards, and most especially links to questions, have suddenly become blue.

It's getting a little strange. I keep thinking I'm on some other network site.

Question links are blue:
