So the actual reason I remembered tumblr existed was because I was having thoughts about the Royal Scandal series and cultural appropriation / racism and my partner told me I should tumblr about it.
This is Catherine, the one Royal Scandal character (outside of a handful of nameless background characters) that has a darker skintone.
Catherine also happens to be a vaguely antagonistic figure and is associated with (black) cats, as they represent the Cheshire Cat from Alice in Wonderland. They are also the only (afaik) RoySca character who does not have a canon gender listed, making them androgynous/ambiguous/nonbinary. Considering that the gender binary as we know it is defined by white patriarchy, and is used to degender and dehumanize people of color, Catherine being the only genderless character is echoing a long tradition of the degendering of POC.
This is Alam, who is based on Aladdin. The original Aladdin itself is a story by a French man: it originated as an Orientalist tale by someone with limited contact with, little knowledge of, and bigotry towards non-white cultures.
Alam himself is a light-skinned man intended to be Arab, a problem in itself. While Arab people may have a variety of skintones, including lighter skintones, the lack of overall skintone diversity points to colorism and light-as-default rather than a deliberate choice by the creators.
His depiction is further problematized by making his 'Jasmine' a wealthy white woman - Olivia - from a Europe-analogous country. He ends up abusing her due to being cursed by a magic ring, resulting in the neglected and abused Olivia murdering him.
As far as I am aware, Alam and his song, Magic Ring Night, which attempts to use "Oriental" musical motifs and some Arabic, were not created in consultation with anyone from any Arab and/or Middle Eastern background.
Nina is a girl from a small tropical island village who is clad in what appears to be an amalgamation of indigenous dress from a variety of cultures that remain unnamed, uncredited, and unthanked, their traditions mined and robbed for artistic inspiration by non-indigenous creators.
Much like Alam, she is light-skinned, again a decision likely not made as part of consideration of cultures she is inspired by or coded as. She, much like Alam, is a poor person from a non-white culture who falls in love with a wealthy white European. This ties into a long-standing trope of non-white people being "saved" and "civilized" by their white lovers.
Both Alam and Nina also go through a transformation where, as part of gaining power (Alam) or fitting into European society and appealing to her love interest (Nina), they discard their cultural dress in favor of European clothes.
This story of (attempted) assimilation into whiteness to gain status, wealth and love ignores the violent, forceful assimilation that indigenous peoples have endured, and still face. It rewards characters for approaching whiteness, and, in Nina's case, distinctly treats her European dress as a superior adornment to her cultural dress.
I do not believe that KANON69 and Rahwia created Royal Scandal while understanding these implications of their work, but they did not consult people of the cultures they attempt to depict, and their biases are reflected in their work.
I hope that more Royal Scandal fans can acknowledge the harm in the depictions of non-white cultures and characters in the series.
