It hard to gauge the true color of your green beauty from the picture. Here's are 2 links to a green cattleya hybrid- Blc. Greenwich 'Elmhurst'.
It's not the same thing- the lip on yours is more ruffled and more magenta but as you can see the 2 pictures in the links are not identical.

Many growers in Hawaii and Florida have green catt hybrids. It may at least give you a clue as to similar hybrids.
You won't be able to find it's name for certain, but lots of folks on OB give their NoID orchids names of their own-- just so the NoIDs don't feel unloved
