As of iOS 6.0 there are two methods that allow you to change the color of the section indexes and the background shown when you drag the scrubber.

if ([tableView respondsToSelector:@selector(setSectionIndexColor:)]) {
    tableView.sectionIndexColor = ... // some color
    tableView.sectionIndexTrackingBackgroundColor = ... // some other color
}

Example of [UITableView sectionIndexColor].

if ([[self tableView] respondsToSelector:@selector(setSectionIndexColor:)])
{
    // In iOS 6 there is a own method available to set the index color
    [[self tableView] setSectionIndexColor:[UIColor whiteColor]];
}
else
{
    // Use this hack in previous iOS releases
    for(UIView *view in [self.tableView subviews])
    {
        if([view respondsToSelector:@selector(setIndexColor:)])
        {
