DID I SOUNDS SMRT??
My guess is it will probably go more green.
Sometimes you can keep the yellow by pounding it with light or going Ultra ULNS. Notice the 2 ultras.
My guess is naturally that coral is green. almost 100% of the time these acros that look yellow are just a little bleached from light shock or shipping. Once in a while/rarely the coral will actually be yellow.

I bought a maricultured yellow piece at MACNA in Atlantic City 2 years ago. At the time I was running 10K 400 watt XM bulbs....par monsters. This coral could take it less than a foot away from directly under the bulb in Lumenmax Elite reflectors and was as bright as a ripe lemon. As I increased the photoperiod it exhibited orange tips. Everything else in the tank suffered from the intensity and duration.
When I made the switch to Radium bulbs on Galaxy ballasts everything else colored up, but the bright yellow seemed to have faded and tips are now more green. True yellow SPS corals can definitely handle high lighting, and probably need more intensity found in the full spectrum range that many of us shy away from because of the yellow tint to the aquarium. I remember when snorkeling in Fiji that one of the brightest yellow SPS corals I had ever seen was a mere 3 feet under water at low tide in very intense sunlight....not branching off of a reef wall but right on top of the rock structure getting the sun's full intensity all day long.
