Can you un-brown corals?

Happy Day!
I just got a new light system so I should be better for the nem and coral. The light is a fuval sea. However, watching. BSRtv I discovered the wrong light can lead to brown coral.

if the coral does go brown, can you get their color back? did I misunderstand the show? If I purchase zoa’s and a nice fancy store with perfect lighting, could they have a bad response in my tank with different lights?

I currently have my light with the factory setting for color boost. I only have a leather finger coral and 2 Duncan.

From my understanding, as long as the coral isn't too far gone, the zooxanthellae can reproduce once the conditions improve. Generally this reproduction will result in improved health and coloration of the coral.

yes, you can un-brown a coral. proper lighting and stable water parameters will bring it back. some trace elements help with coral coloration as well.

Yes, as long as the coral is not dead or dying, you can get color back on brown coral (or new colors on other coral) with different lighting. If you're adding a new light that is more intense than your previous light, it's a good idea to slowly ramp up the intensity over time. LPS and softies like your Duncan and Finger Leather generally do best under low-moderate lighting, so I don't think you need to go too high with the intensity.

Zoas will likely look different under different lights. They'll probably be a little less vibrant under the Fluval Sea than a nicer LED array, but they shouldn't brown out unless something else is wrong in the tank.
