Your pictures are very blue. hard to tell. Can you take a picture with daylights on? Most anemones come in somewhat bleached. It's because they keep them under very poor lighting or none at all until they ship them to stores, and many stores don't go out of their way with lighting either. Not to mention transferring from one system to another, and in many cases, less than ideal parameters. It's not the fault of the store. Human beings in general really.
That said, you can color them back up fairly easily with proper parameters and lighting.
