Alright Harumi's makeup and hair
So my personal headcanon for her hair is that she had to drink a magic tea that leeched the color but strengthened it
It seems like something that would happen in Ninjago as like a ritual for the Royal family
Her hair was already pretty pale before but it had much warmer undertones and then once she was in the royal family it had cooler undertones
So it definitely had what little color it had stripped out through bleach or magic
As for her hair styles, they mainly use buns and not even really complicated ones, they just seem complicated because they are twisted up and held in place by hair sticks
(As someone who has length waist hair though I can tell you the hardest part of those styles is the tension that puts on your scalp, this is why I headcanon that magic tea because how the tension typically causes hair loss)
Her makeup as a princess is a really interesting choice
(definitely the result of not proper studying of the culture and instead just appropriating it because while yes pale skin is more desirable and they would use white face paint in those cultures that was more for entertainers and sex workers)
Her make up is more rooted in chinese culture (same with her clothes, that is not a kimono it's a mix of a hanfu (chinese) and a hanbok (korean))
A pale face made to look more round with blush centered on the cheeks is much more popular in china especially if they had a painted a flower on her forehead (with how much they did the lotus motif I am honestly surprised they didn't)
Now her Quiet One make up/thing?
I'm thinking grease paint
I'm afraid the stuff I got from college has no brand so I can't even recommend it but like whatever that brand is could hold the shape and color through a fight and only need mild touch ups
Like here is some looks I have worn for that class that required a full face scrub to get off and there were still traces
Like I could have probably gone swimming in that and not lost much saturation
So I think she uses a red greasepaint and whatever brush she uses is permanently red for life (jk grease paint stains come out with coconut oil)
