First, I must say I have very little ( near -> 0 ) experience with Curses and/or POE.

It depends on what you really want to achieve. If you want to highlight portions of the text, than I can't help you with that.

But if all you want is to change the background and foreground of the text than is simple, change the line that defines the window to:

 $_[HEAP]{tview} = $_[HEAP]->add( 'win1', 'Window' )->add(
     'text', 'TextViewer',
     -wrapping => 1,
     # -width    => -1,
     # -height   => -1
     -border => 1,
     -y      => 1,
     -bfg    => 'red',
     -bg     => "white",
     -fg     => "green",
 )

But, probably you already know that :)
