This question came to my mind when I was watching the latest episode (21) of Sailor Moon Crystal: What is the real color of Neo-Queen Serenity's hair?
In the old anime it was always yellow, similar to Usagi, but seeing her appearance in the new anime confused me. Is there just a wrong color in the old anime? Also thinking Sailor Moon would be Sailor Cosmos adds some wondering to this, but is probably unrelated transformation. There are many pictures for both colors.
Thanks for answers!
