Which is the default bar tint color in iOS 7

Question

I would like to set the background (bar tint color) of a toolbar in iOS 7 to the default color (white, light gray) as shown in the screen shot below.

I tried both color variants, but none matches the default color which looks like this:

Which would be the correct color to specify here?

self.navigationController.toolbar.barTintColor = // ????

self.navigationController.toolbar.translucent = YES;
