You can use delegate method : 'scrollViewDidScroll' and add

//get refrence of vertical indicator

UIImageView *verticalIndicator = ((UIImageView *)[scrollView.subviews objectAtIndex:(scrollView.subviews.count-1)]);
//set color to vertical indicator
[verticalIndicator setBackgroundColor:[UIColor redColor]];


//get refrence of horizontal indicator

UIImageView *horizontalIndicator = ((UIImageView *)[scrollView.subviews objectAtIndex:(scrollView.subviews.count-2)]);
//set color to horizontal indicator
[horizontalIndicator setBackgroundColor:[UIColor blueColor]];
