They're not designed as "light skinned poc" tho, they're just made pale because Hoyoverse doesn't think people will open their wallets for brown waifus.

Which is a shame, because the lack of skin tone variety is starting to make their designs blend together. The new hydro girl just looks like even more pale Nilou, new dendro guy is just human Tighnari with better hair. The new Geo girl looks cute, but the glow effect caused by whatever that skill is just makes her look like she's made of gold because of the lack of contrasting colors.
