title: What is the default TableView section header background color on the iPhone?
body: <p>I want to customize TableView section header and to leave default background color. I use  - <code>(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)</code>section. I need to change font size depending on device (iPad or iPhone). For this purpose call next function:</p>
  
  <p>[UIColor colorWithHue:0.6 saturation:0.33 brightness: 0.69 alpha:0.6].</p>
  
  <p>But I found these values manually. </p>
