speckled purple orchid

Lovely flower.

i'm not an expertise in anything about plants or orchids, so, noticing the spots and shape arose a question: are these all from same type, just different colors?

The mokara ones are the same type. This one, the red and the orange. But the gardener from the orchid nursery who saw me taking notes told me that the orchids are all hybrids. Vanda, aranda and mokara. I saw on one website the same orchids in Saigon, they labelled the orchid as mokara.
