>>3138301I can't recall if her hair color is mentioned in any of the novels, but it's true that it doesn't seem like her hair was definitively purple in the beginning (pic related: first color illustration of Nagato in the first LN). I still see the early LN illustrations as purple but I probably have some retrospective bias.
It would be nice to see a chronological order of all Ito's Nagato art. Her Nagato's hair is less saturated and more reddish than the KyoAni design, but they're both beautiful hues of slate purple. I really love Nagato's hair.
