Is there a list somewhere of the UIManager.getColor() keys for Swing? I can't seem to find it online, just occasional references to strings like "Panel.background" and "Table.selectionBackground".

I was looking for the same thing and found this page as well as an excellent overview of all these properties on http://nadeausoftware.com/node/85.
I don't think there is a defined standard set of keys. But you could try this bit of code to list the ones currently available in alphabetical order:
List<String> colors = new ArrayList<String>();
for (Map.Entry<Object, Object> entry : UIManager.getDefaults().entrySet()) {
if (entry.getValue() instanceof Color) {
colors.add((String) entry.getKey()); // all the keys are strings
}
}
Collections.sort(colors);
for (String name : colors)
System.out.println(name);
This produces a list too long to reproduce here.
@mmyers got me inspired. Here's a short program to list the UIManager defaults in a sortable table.

this.value = e.getValue();

public Class getValueClass() {
if (value == null)
return null; // ?!?!?!
return value.getClass();
}

// doesn't handle arrays properly
if (value == null)
return "";
return value.getClass().getName();
}
}

{

l.setText(String.format("Color 0x%08x (%d,%d,%d alpha=%d)",
c.getRGB(), c.getRed(), c.getGreen(), c.getBlue(), c.getAlpha()));
return cell;
}
else if (e.getKey().endsWith("ont"))
// possible font, not always ".font"
{
// fonts are weird, for some reason the value returned
// in the entry set of UIManager.getDefaults()
// is not the same type as the value "v" below
Object v = UIManager.get(e.getKey());
if (v instanceof javax.swing.plaf.FontUIResource)
{
javax.swing.plaf.FontUIResource font =
(javax.swing.plaf.FontUIResource)v;
l.setText("Font "+font.getFontName()+" "+font.getSize());
}
}
}
setDefaultColors(cell, isSelected);
return cell;
}
}
public static void main(String[] args) {
final EventList<UIEntry> uiEntryList =
GlazedLists.threadSafeList(new BasicEventList<UIEntry>());
for (Map.Entry<Object,Object> key : UIManager.getDefaults().entrySet())
{
uiEntryList.add(new UIEntry(key));
}

// build a JTable
String[] propertyNames = new String[] {"key","value","className"};
String[] columnLabels = new String[] {"Key", "Value", "Class"};
TableFormat<UIEntry> tf = GlazedLists.tableFormat(UIEntry.class, propertyNames, columnLabels);
EventTableModel<UIEntry> etm = new EventTableModel<UIEntry>(sortedUIEntryList, tf);
JTable t = new JTable(etm);
TableComparatorChooser<UIEntry> tcc = TableComparatorChooser.install(t,
sortedUIEntryList, AbstractTableComparatorChooser.SINGLE_COLUMN,
tf);
sortedUIEntryList.setComparator(tcc.getComparatorsForColumn(0).get(0));
// default to sort by the key
t.setDefaultRenderer(Object.class, new UIEntryRenderer());
JFrame f = new JFrame("UI Manager Defaults Viewer");
// show the frame
f.add(new JScrollPane(t));
f.pack();

}
}
This program is the best I've seen for visualizing the UIManager values (e.g. Fonts, Colors, Borders): http://tips4java.wordpress.com/2008/10/09/uimanager-defaults/
It lacks search, but it can filter by component or value type, which is pretty great.
They are kind of Look and Feel implementation dependent. Look in BasicLookAndFeel.java for the basic keys. Don't expect all PL&F to behave the same, or even remain the same between versions.
