Acropora ID - Color Change

[Syoung]

I've had this acro about 3 months, and when I bought it, it was completely red. Little to no corallites.

Original color from LFS and tank pre-alk crash​

A few weeks ago I had an alk crash, and half the coral is currently lacking tissue. But that's besides the point.

With the alk higher and stable, it's recently started to turn fluorescent green! Any insights on what this is?

As well as the scientific type if possible!

Looks like an ORA Red Planet to me. It is all red in high light but develops green undertones in medium or lower light. Not sure on exact type of acropora. Another possibility is ATL Shades of Fall.
