I think that besides too few color options, there are also too few hairstyles and too few options for the facial features.
I tried to make Merida from Brave today and realized that even though the game has curly hair options, I could barely match her hair texture. Then I tried to make Rapunzel from Tangled and found out that there are almost no nice combinations between the front of the hair options and the braid I wanted to use for her. I also noticed that it's very difficult to match the face structure, eyes, and blush well for both of them.
