Oh come on... minus buttons and a few extra boxes its exactly the same
Besides, it had to be done for two reasons that are of greater importance than visual details, and that is server performance & security.
EDIT: I've removed all remaining blue elements and fonts which I noticed. I've also shaded the buttons a little so that they don't scream red as much as they did before. Just to a hard refresh (ctrl+f5) on board index, topic view and forum view and everything should fall into shape. If you encounter any blue elements that I accidentally missed, let me know!
