The dark bar itself isn't really the issue, I'm all for a dark layout for GitHub. But as it is right now, with the header being dark and the rest light, it just looks very jarring and distracting to me. Your attention keeps being pulled to the top bar, but that's not where the real content is.

At first I assumed this was part of an incremental change to go fully dark, although I'm not sure why they would release it part by part.

But then a tweet [0] seems to imply that it's not gonna happen anytime soon.

That's what I thought too. Dark means the repo is private. If you fuck up, the world won't see

White means, anything you do here is publicly visible.

Seriously github.com can we please use the black to give some meaning.

I don't want my public repos to have black headers.

The problem that I have with it is that I can no longer distinguish a webpage as being from public Github and enterprise Github with a cursory glance.
