Going forward, we can change colors or the style entirely if anyone has ideas. My only concern with having several very different styles is that it becomes harder to support and can get confusing when we're discussing site features but seeing different things on our screens.
Personally, I'm fine with it like this. I think it fits the Black & White theme and goes well with the red accents, and I'm pretty much used to it since I chose the similar option from the last big update. I can understand why it would take some getting used to though, especially after all the years of the vbulletin blue it used to be.
I still got enough of my blue fix from the favicon on the tab, but that's not there anymore either for whatever reason (it does show on the Admin page though). It made the tab stand out and easy to locate for me, which is nice since I tend to have a lot of tabs open (too many most of the time lol). It does still show up on the shortcut icon though.
