Honestly asking, isn't this stuff usually Japanese characters? I dunno if theres even "data" they could use for other skin tones
Ethnicity is sometimes incorporated, that is, some distinctions would be necessary if there was a documentary manga about a match in an Olympic Games played by teams from multiple parts of the world, and in that case an American players might be given smaller eyes or extra wrinkles in face, or African players might be colored darker than other characters, Chinese players could be drawn with slightly different shapes of chins, etc.
But the default is unspecified or an averaged, most simplified shapes and forms that the author uses in their own cognition.
Yes. What's your point?
> [...] and not meant at all to represent darker-skinned races.
No one ever claimed that. The question to my post was simply where to possibly get data from for "darker skin tones". Ganguro seems like an option because ... well, darker skin tones? Care to elaborate why you bring up "representation of darker skinned races" up in this context?
If we understand the ancestor comments as asking for more diverse representation, then no, because ganguro and many other anime archetypes and their clothing and accessories are ultimately Japonicentric, in the same way that you might consider angels and demons contrasted against each other post-antiquity Eurocentric.
My opinion on the matter is that it's not necessarily a worthy goal, but there is a more distinct difference to representing people of different races even in anime faces than just skin tone.
