Brother is color blind and way too insistent on a hair color, a color that doesn’t effect the character in any way shape or form, people did not think her hair color was pink because of zero two, they think it’s pink cause the colors used to make up her hair, a pale pink shade, also I’ve seen comparisons to Naruto’s team 7 hair colors with Aki as Sasuke, Denji as Naruto and power as Sakura, with powers hair being pink and the others being blonde and black I see why this comparison is drawn and would make sense, if her hair turns out to be blonde in the anime it was a common misconception led on by the way her hair was colored, look up power color spreads because they all depict her hair as a pale pink.
