All JTrees use a DefaultTreeCellRenderer unless told to do otherwise.
So, you can do this:
DefaultTreeCellRenderer renderer =
(DefaultTreeCellRenderer) myTree.getCellRenderer();
renderer.setBackground (myColor);
Other alternatives include subclassing DefaultTreeCellRenderer, or
setting the UIDefault for the property "Tree.textBackground".
If your JTree uses a different cell renderer, you'll have to figure out
how it determines which background color to use, and how to set it.
(It would be implementation-dependent.)
