Mac OS X has had the option for a Blue or Graphite appearance for years. The Graphite theme replaces the red/yellow/green buttons and blue selections with grey. It's the same neutral tone that's carried-over to the Pro apps. http://www.dslreports.com/forum/remark,9439970 I want it in iOS 7 because the dark keyboard and Safari Private Browsing Mode look so much better and is easier on the eyes when in a dark room or at night. I'd even be fine if the option were restricted to system elements and built-in apps, so developers could do whatever color scheme they want. What do you think?
