In the site design release post Japanese Language New Site Design, this colour scheme was shown:
I imagined that one colour would be for the main site, and one for the meta site, since for other SE sites the main site is coloured differently from its meta. (I think the main site's colour is also related to the Chat site?)
But it seems main, meta (and Chat) are all grey for our site.
Is this (both sites (and Chat) being grey) intentional? Where can I see the blue background? Is there a display options tab somewhere?
