Why can't I customize the color cast for the UINavigationBar?

Question

I want to change the color in the navigation bar, and the documentation says that you are not trying to change the alpha value. So, how can I set a color that is not SDK-defined values ​​(for example, [UIColor redColor], brownColor, etc.), if all the constructors provide an alpha range value? I tried to get the current alpha value, but that didn't help. When I use my own color, this makes the navigation bar look like x-ray (scraggy, black-on-white).

[self.navigationController.navigationBar setTintColor: [UIColor brownColor]];
