I am going to go off an a tangent about that.
The Orcs in the Warcraft series are green-akinned. Their culture is also heavily inspired by African culture. Meanwhile, the blue-skinned Trolls speak with Jamaican accents and have a culture clearly based on Caribbean culture. Meanwhile, Native Americans were turned into cow-people, and East Asians were all made into Pandas.
The humans? They are all fair-skinned European Christians.
Fantasy/Sci-Fi has an endemic race issue that has persisted for decades, particular in the strain that has roots in D&D. Only white people get to lay claim to being human, everyone else is turned into green-skinned monsters that humans can feel free to kill on sight. European culture is seen as the norm, while different cultures are "othered".
This is compounded by a trend, particularly in Japanese pop-culture, to use dark skin to demark characters who are not human. It is common to see works where all of the fair-skinned characters are humans, while the dark-skinned characters are all animal people, demons, or aliens. Taje FFXII for example: the only dark-skinned character is a rabbit-woman.
