Saw some of these at the Manatee River OS show. Yikes! The link says they aren't dyed, but they certainly look it- just like colored carnations. The vendor had some in their display, but we made them take them out per the show rues. They also said they wouldn't bloom that way next blooming. So whatever it is that induces the color must be repeated at each spike initiation???
I personally thought they were hideous, but can believe that non-orchid folks would go nuts over them.
