There may have been a pink Tsum mission. I can't remember. But if there wasn't any, it at least future-proofs the category since there are a decent number of them currently and they can be easily identified. I would have kept gray as another future-proofing, but it's harder to distinguish a white, black or gray color without actual testing.
