To my knowledge there is no such thing as a true black Phal.
There might be a real dark purple.
You want something that comes real close to a black orchid try Dracula vampira, Dracula roezelii, and Dracula anthracina. You could also go for the "black" variety of Maxillaria variabilis, or Maxillaria schunkeana. Catssetum tenebrosum is also close to being black.
