Japanese Colorism is constant and ever present and always gross as hell
Gym leaders are more often than not adults, SuMo was the only one with replacements that were largely kids.Personally I'm far more offended by her suggestive posing given that she's likely no older than 15, but then again I know what time we live in, people will sexualize anything.
However I'm just rolling my eyes so hard at these lame ass defense attempts about color palette and whatever such bullshit. In that fan art she's a tan white girl, maybe a Latina.
Also couldn't help but crack the fuck up at "if anyone has studied art, you may have come across that name" in regard to warhol. I would say that was sarcastic but...
