The background color property is ignored on a <code>UINavigationBar</code>, so if you want to adjust the look and feel you either have to use the <code>tintColor</code> or call some of the other methods listed under "Customizing the Bar Appearance" of the <a href="http://developer.apple.com/library/ios/documentation/uikit/reference/UINavigationBar_Class/Reference/UINavigationBar.html">UINavigationBar class reference</a> (like <code>setBackgroundImage:forBarMetrics:</code>).

Be aware that the <code>tintColor</code> property works differently in iOS 7, so if you want a consistent look between iOS 7 and prior version using a background image might be your best bet. It's also worth mentioning that you can't configure the background image in the Storyboard, you'll have to create an <code>IBOutlet</code> to your <code>UINavigationBar</code> and change it in <code>viewDidLoad</code> or some other appropriate place.

I want to change the color of the navigation bar color, but I'm not sure whether or not I should change the tint or the background. I know iOS 7 is going for a more flat design (even <a href="http://www.webdesignerdepot.com/2013/07/how-to-transition-app-designs-to-ios-7/" rel="noreferrer">recommending removing gradients</a>), but I am having trouble deciphering the two. Even if I set a background color, it doesn't do anything.

In this image, the background is set to green, but the bar is still blue:
