Kids in color! Oooooh!
When I design characters I usually think of them in color. I knew I wanted Gretel to be super-blonde, so that when she's in the forest or in the witch's dank old house her head will silhouette nicely. Also, a lot of, a LOT of gals in old fairytale illustrations have white blonde hair like that (maybe for the same reason?), so I lifted the idea for myself. Hansel still looks like a jerk but I'll get into him more soon.
