the LTAs that are that color are not supposed to be that way. they are "bleached" as the term goes, and lacking a significant amount of their zooxanthellae. the anemone will lose the blueish tint once it begins to regain its zooxanthellae and return to a more natural rich brownish green.
as for the two heteractis crispas you have, one is looking natural and on its way to being a healthy darker green brown, the other one...the one thats as yellow as your yellow tang....is not so good. most definetely dyed. not necessarily fatal, but never a good thing.
