Some extra styling suggestions for admin pages

I added the following to the end of style.css because the inherited grey tabs and tables from system.css were annoying me:

/*
** override tab colors from modules/system/system.css
*/
ul.primary {
  border-bottom: 1px solid #bbb;
}
ul.primary li a {
  background-color: #D1CC92;
  border-color: #bbb;
  border-width: 1px;
  border-style: solid solid none solid;
}
ul.primary li.active a {
  background-color: #ffffe3;
  border: 1px solid #bbb;
  border-bottom: #ffffe3 1px solid;
}
ul.primary li a:hover {
  background-color: #E5E6C2;
  color: #333;
  border-color: #ccc;
  border-bottom-color: #eee;
}
ul.secondary {
  border-bottom: 1px solid #bbb;
}
ul.secondary li {
  border-right: 1px solid #ccc;
}
ul.secondary a.active {
  border-bottom: 4px solid #999;
}

/* table degreyed */

tr.even {
  background-color: #EAEBC7;
}
tr.odd {
  background-color: #E5E6C2;
}

/* style messages (requires the 
   page.tpl.php fix to return messages) */

.messages {
  font-size: larger;
  background-color: #C06700;
  border: 1px solid #ccc;
  padding: 0.3em;
  margin-bottom: 1em;
}

This does not handle all tables, but it did fix the ones I look at the most often.

I also added basic styling for messages re http://drupal.org/node/171359.
