UIColor *textDefaultColor = [UIColor blackColor];
    CGColorRef textDefaultColorRef = textDefaultColor.CGColor;
    NSString *textDefaultColorStr = [CIColor colorWithCGColor:textDefaultColorRef].stringRepresentation;
 
    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    [userDefaults setObject:textDefaultColorStr forKey:@"textColorKey"];
