Shireen and Honey could be almost impossible to tell apart in many cases. If Shireen was made with one or both parents being alba you easily put it in the same color range as a typical Honey made with a typical pale primulinum. Honey made with primulinum var. purpurascens and a dark philippinense could be intensely colored. I don't see anything in this flower that rules out being Shireen, but if there is some possibility of a mix up it would be hard to sort out. If you had any Paph Judge Phillip or Paph Carol Booth around, maybe a few others, they could be indistinguishable too.
