Forum:What color should the children's hair be?

I've noticed that on most of the children's pages, and on the "List of characters in Fire Emblem: Awakening/Fates" pages, children have a neutral gray hair color (the exceptions being Lucina and Shigure, for obvious reasons, and Midoriko, Matoi, and Syalla, for less clear reasons (especially Syalla, given that white is neither the hair color of her father nor Tharja)). Is this done intentionally to avoid spoilers, or because we don't have portraits of them with their canon hair colors (IIRC, the Awakening children used to have theirs, but maybe not)?

I'm asking because I generated portraits of all the Fates children with their canon hair colors for personal reference, and I'm wondering if I should upload them to this page: http://fireemblem.wikia.com/wiki/List_of_characters_in_Fire_Emblem:_Fates
