I put a link in with my guess if you are looking to verify it. It might not be P. vaughani. But it is Psammocora. It could be Psammocora profundacella aslo. Definitely not a Favia or War Coral.

The color will not matter when IDing a coral, if you go by it then color can even be confusing.
I would say this is an SPS, but is can be debated like Cyphastrea, the polyps are just in between that decision.
