Got a green bubble anemone a few days ago. It rooted within a few
hours with its foot buried at the back of a little cave in the
rockwork. There is now a strange lighting related routine that seems
to go against the text books:

It is very likely that anemone needs to adapt to new light conditions. You
should give it one month or more to see how will it adapt. Probably before
you bought this anemone it didn't get very much light.
The other possibility is that light spectrum of your aquarium is much
different from the spectrum it used to be exposed to. That means that
pigments in its tissue do not protect it enough from the light in your tank
so it needs to develop pigments adapted for new spectrum.
