What makes a coral turn green?

[Ratpack]

I bought a frag of the Pearlberry Acro and it was white with purple tips. Now that it is in my tank and has been there for a month or two, it is all green. It has been high in the tank and now in the middle, no change?

I am running LED's
SG @ 1.026
Alk 7.5DKH
Cal 440
Mag 1350

All my other corals are pretty true to their colors that are expected. I even got another Pearlberry from someone else and it stayed white with purple tips.

Any thoughts?

I am by far no expert but my first guess would be your light spectrum. LED is a broad term more specifics may help.

Low par usually

It is getting about 220 PAR, what should a Pearlberry get?

Double that and you will get it to color up for sure, the minimum required to get it to color up? No idea.

Funny thing is mine has turned greenish as well. If anyone has an idea, i would also love to hear why.
