UIColorFromRGB(rgbValue) Normally you want to use your own color as the system color doesn’t look nice. Here is a very useful macro for setting RGB color.

UIColorFromRGB(rgbValue).m

// Define somewhere in a header or macro file included on prefix.psc file or put it somewhere at the beginning of AppDelegate.m and use it to create any UIColor object with whatever RGB color you want. Below is an example:
// Get colors at http://colorschemedesigner.com

#define UIColorFromRGB(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0 blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]

// Usage !!!
[[UINavigationBar appearance] setBarTintColor:UIColorFromRGB(0x067AB5)];
