How to add colour to the navigation bar ? I need to implement this for iOS 4 and above.

In iOS < 5 you can set tint color of individual navigation bar directly, e.g.:

// self is a UIViewController
[self.navigationController.navigationBar setTintColor:[UIColor purpleColor]];

Once you don’t need compatibility with iOS 4.x you can use appearance proxy for UINavigationBar. This would work for all navigation bars in the application:

[[UINavigationBar appearance] setTintColor:[UIColor purpleColor]];
