Do they regain their true color?

[Leviathan_XE]

I've just finished moving my old tank to a new one and I'm sad to say that my old tank was a little neglected. I had some shrooms in there that had detached from the rocks and stuck to the side of the glas in an attempt to get more light. A few of them made the transition but of course they are nothing like their original color. When I first got them they looked great even though my old tank only had 2x96w pc lighting on it, which only had the actinic on mostly. The new one has 6x54w T5s. How long will it take for them to color up or will they never regain the color they once had?

Not sure about corallimorpharians, but sps and lps will regain their colors over a few months. *I have been lucky and had a browned out Tri-Color regain green, purple, and red tint in a little over three days*
