I've just noticed that all my page and post titles and subtitles change colour when the browser is reduced to the smaller screen size. They're usually red (for .entry-header .entry-title and.entry-content h3) but then they change to grey, and show that they've been changed to 'body' too.

I realise it must be something to do with the mobile settings, but i can't find where to change it in the Twenty Twelve theme (for my 2012 child theme).
Any ideas? Or is this standard practice for mobile settings?
