I think lighting. I have had many purple/yellow SPS turning green when first introduced to a new tank...After acclimating to the environment then the color comes back if the conditions are right...Sometimes even better color than in previous tank...

Correct just lighting.
Many say that a weekly dose of some iron will do the trick to keep the yellow but never worked in my system.
My acros that are yellow stay yellow just to keep them close if not over the 350 par.
No3 between 5ppm and 10 ppm, Po4 at 0.06.

iron will green a yellow coral ime.

just give it a ton of light and keep nutrients lowish.

5-10 no3
.02-.15 po4

if you want paler yellow... go for 3ppm no3.

Higher nutrients will make yellows green. Higher par and the right spectrum will help yellows come out more too.
