    Hi
    I′m making the brand of my site change it′s color depending on the category it′s showing.
    I need to get the parent category for single posts, so that I can tell my css what class to show.
    Here is the code:

    <?php
    if (is_front_page() ) {
      $cat = "home";
    } elseif (is_category()) {
      $cat = get_category_parents($cat, FALSE,'',TRUE);
	  } elseif (is_single()) {
      $cat = get_the_category($cat->parent);
	  $cat = $cat[0]->slug;
	  echo $cat;
    }
  ?>

    Category pages are working fine, but I can′t make single to work.
    Also, I don′t want to type each post ID because it will be a nightmare!

    Any ideas?
    Thanks!
