Favia Brain has tint of Orange. Why?

I know that some corals can kinda change colour.
I had a hammer that changed from a kinda tan to a green. Just guessed it was the lighting that effected how it grew or something like that... Hahah, I have no scientific explanation.
 
It could have imported some neighboring zooxanthellae, who knows. Or perhaps lost some and now the non-dominant residents are starting to flourish.

Captive corals lose and gain color all the time depending on changes to their local growing conditions.
 
I've had a couple corals change colors on me too, I wouldn't worry too much unless it starts to turn white
