I re-watched it several times trying to make sure they were in fact pink cloaks and after seeing some other cloaks, the mountain and Tywin himself for example, I am certain that these cloaks are PINK. Look for the scene when Arya scolds Jaqen for becoming a guard, his cloak and the men far off in the background (Jaqen says, "You did. I did, and here we are..." then pink cloaks walk into the shot). Then look at Lord Tywin's when he arrives at Harrenhal or the Mountain's when he is choosing who to kill next.
I could be wrong and the cloaks may just be faded.
What do you think?
