Wwc Gi Joe Favia Question

[Boco]

I just got this Favia on Tuesday (2 days ago) got it aclimated and placed in the bottom of the tank. My concern is that the coral had a little bit of green around the edges but now all Color seems to have gone. I'm not the most familiar with Favia in general and im still in the 10 day promise to live. It's in a 15 gallon tank with a Fluval marine 15" LED light.

A few other pictures, I think I'm only seeing the boney structure no flesh..

That's what I thought. I have emailed WWC already but they take a day to get back it seems. I just wanted to make sure I was correct. I was able to find more info last night.
