I am quite sure that this is just wishful thinking.
With most GUI packages like QT or GTK even being able to change the color of
the *whole* editable box would not be possible; colours are managed by the
windows manager. I don't think Java would be an exception to this and you
might be better off splitting your multi-line editable box into several
single-lined boxes with distinct colours. It means you then have to write
some more code, but at least colouring then becomes simpler.
