You can use NodeMouseClick event to set the background color of the selected Node.

Define a class level TreeNode member

TreeNode node = null;

And use the logic given below,

private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
 {
    if (null != node)
     {
         //Reset the color when selected node changes
         node.BackColor = Color.White;
     }

     //Set the currently selected node color
     e.Node.BackColor = Color.Green;

     node = e.Node;
 }
