Long tentacle... sick... or part chameleon?

[doch]

SO, I fairly recently picked up a couple of anemones... one LTA, and one BTA... the BTA got caught in a power head (damnit) lasted for a few days and went out... in the mean time, the LTA has gone from mostly brown with a little bit of green to mostly white with an almost purple hue. Still nice and firm and fairly sticky, seems to want to eat, but I'm not 100% sure if it is actually taking in the mysis that I squirt its way. If I give it a large chunk of shrimp, it holds onto it but eventually lets them go. Overall, it looks healthy, just changed colours. Up until this weekend, I didn't have enough light on the tank... that has now been fixed. Any thoughts?
