Thanks for the article, gave it a quick read. In that case, there are a few things to consider:
-This character is actually more on the introverted side, and wasn't intended to be rebellious (at least, not on the inside!). Not the kind of person to be driving motorbikes away from explosions, but more the kind of person who prefers to text than speak.
-I'm at a crossroads at the moment whether the setting will be in Japan or the UK. But what I do know is that everyone does have different coloured hair too
-My comic is black and white, so the hair dye would only appear on the cover page.
I mean -- I don't personally see it as a necessary change, and I like how the red goes with the rest of the colour scheme. But then again, I don't want to come off as offensive to a culture that, admittedly, I don't understand that much. So maybe I should change it then? But at the same time, an Asian character with partially dyed hair but is actually an introvert could be seen as breaking the mould? Ugh, I dunno, decisions are hard
