How to change color of return key of keyboard in iPhone?

There is actually no official way to change the color. All you could do is write your own keyboard.

There is no official way to change the return key color. But you can have different options for return key, as UITextField has a property returnKeyType.

yourTextField.returnKeyType  = UIReturnKeyDone;

And these are the other allowable types

typedef enum {
   UIReturnKeyDefault,
   UIReturnKeyGo,
   UIReturnKeyGoogle,
   UIReturnKeyJoin,
   UIReturnKeyNext,
   UIReturnKeyRoute,
   UIReturnKeySearch,
   UIReturnKeySend,
   UIReturnKeyYahoo,
   UIReturnKeyDone,
   UIReturnKeyEmergencyCall,
} UIReturnKeyType;

You can read Apple's documentation here. This SO post also explains this.
