You can use the picker delegate method.

       -(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
       {
              mString.text=    [arrayNo objectAtIndex:row]; //mString is a NSString defined and the arrayNo is the NSArray that contain all your color data.

       }

Now you have the selected value in your mString object then use that object in the alert message.
