I'm a little confused by the name on this one; I suppose yellow sunsets do happen, but it's not the color I associate with sunsets particularly. Maybe that's the point?
The whole-plant photo below is crappy, but it does at least show that the bloom in the close-up above is a significantly darker shade of yellow than the other flowers on the spike.
The plant doesn't do a lot for me personally, but there's nothing especially wrong with it. Just not my taste, I guess.
Phalaenopsis Fuller's Sunset = Phalaenopsis Taisuco Date x Phalaenopsis Chian Xen Queen (Ref.)
