This was addressed in the patch notes:

However, three Customized Actions (Bitter Coast Recall, Recall of the Crusader, and the one I personally use, Recall of the Galen Wilds) recolor the default blue animation to red, yellow, or green, respectively, and
these worked perfectly fine in Werewolf form.
As a result of this change, you will always recall with the blue color, even if you've selected one of the other colors.
I recognize that it's more involved to explicitly allow Customized Actions which function properly in Werewolf form when most of them don't, but it bothers me every time I port somewhere in Werewolf form and see blue when I see a different color when not in Werewolf form.
