title: Change the background color of a single DataGrid column header
body: <p>I'm using a WPF <code>DataGrid</code> and I want to change a single column header background color, without affecting the others.</p>
  
  <p>I found the following question:</p>
  
  <p><a href="https://stackoverflow.com/questions/4486977/how-to-change-column-headers-background-color-when-using-wpf-datagrid/">How to change column header&#39;s background color when using WPF datagrid</a>,</p>
  
  <p>but this will change all column headers, and I only want to change one.</p>
