Nice pics!
No - lighting is the same. I think that when I put it in there at first, the tank was still newer and since it was new, it was a low nutrient system. I feed quite a bit and the color will shift depending on the feeding.
It does still have a lot of pink, but that's more in the main branches of the colony. The green starts about halfway in the branches and extends towards the tip. All have purple polyps.
