Use the SelForeColor, SelForeColor, SelForeColorChild and SelForeColorChild properties to customize the colors for selected nodes. Use the <fgcolor> built-in HTML format to specify a foreground color for parts of the node's value or name. Use the BackColorChild property to specify the child node's background color.
