UIAppearence only working with system colors in iOS?

I am trying to change the color of the navigation bars in my app with UIAppearance.

But only when I use a system color, it works:

    UINavigationBar *navigationBarAppearance = [UINavigationBar appearance];

    [navigationBarAppearance setBarTintColor:[[UIColor alloc] initWithRed:220.0f green:47.0f blue:40.0f alpha:100.0f]]; // does not work

    [navigationBarAppearance setBarTintColor:[UIColor colorWithRed:220.0f green:47.0f blue:40.0f alpha:100.0f]]; // does not work

    [navigationBarAppearance setBarTintColor:[UIColor redColor]]; // works

Any suggestions?

The method 

colorWithRed:green:blue:alpha:

accept four value between 0.0 and 1.0. So if you have the components from 0.0 to 255.0 you need to normalize with a division by 255.0f.

[UIColor alloc] initWithRed:220.0f/255.0f green:47.0f/255.0f blue:40.0f/255.0f alpha:100.0f/255.0f]

I think you are doing wrong with custom color method, its like this 

[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:127.0f/255.0f green:127.0f/255.0f blue:127.0f/255.0f alpha:1.0f]];
