Come back of my Digitata with multi colors - ID

[jchakraborty]

I was away for 23 days and during that period couple of my corals died, but no fish causalities at all. I saw that my CA went down to almost 320 range and most of the corals were almost covered with Green and Bubble algaes.
Now after last 30/40 days of efforts, things are coming back and I'm excited to see that one of my Green Digitata is coming back alive slowly.

But interesting part is what those RED polyps are there on the pic of the green digitata. Are they come as RED and then turn as Green? Or I'm seeing some new growth of a new species.

Anyone able to confirm is these red pollyps are actually the same pollys as in the green. Meaning red turns to Green after a few days?
