"Why is LEGO using a chocolate color for Co Chang’s skin tone? The Patil twins might be this dark. Maybe. Or Dean Thomas.
Cho Chang was probably put in to the Potterverse to add diversity as an Asian child (name is vaguely Chinese). And generally the Chinese have much lighter skin tones than this.
The earlier minifig isn’t chocolate. And more true at least to the movies.
LEGO needs another crayon in their skin tone palette."
