What colour should tanalised timber fence panels be straight from the
supplier? They're the feather edged variety, not lap.

A neighbout had some installed and they're a faded orange. I was
pretty sure that tanalised (Tanalith E) stuff is green, which seems to
be confirmed by the manufacturers:

So I was a bit surprised when my tanaliased panels arrived and they're
that faded orange colour too. Should they be green?
