Usually I'd say it is lighting related. Things could be burned if they're super sensitive.

Zoanthids usually show pretty good color in most lights. I usually place mine really high, but perhaps yours aren't used of it.

How much color change are you noticing?

i had them pretty high when i had pc's, but then moved them to the lower part of my tank when i got my mh's.

I am not sure if lighting is an issue of a secondary issue. We usually see a bleaching/color changes due to intinse lighting. You may want to check your water quality. High nitrate?
