pink, you can see part of it in the picture. The foot is very interesting... its got some swirling pink colors like its grafted. I can take foot pictures tomorrow if necessary.
Looks like Heteractis crispa to me, most Heteractis magnifica have purple/bluish feet. Also large bubbletips (Entacmaeae quadricolor) can spread out like that and appear like an anemone from the Heteractis genus.
