What color hair did Katniss and Peeta's son and daughter have?

No, this is the correct version. The girl - who's name is unknown - has her Mothers dark hair and her Fathers blue eyes.
The son - who is younger than his sister - has his Father's blonde hair and his Mother's grey eyes.

So, basically, they are a combination of both Parents'

Daughter=blonde
Son=Brunette :)

their daughter has dark brown hair, and their son has blond curly hair

the boy has blonde hair and the girl has dark hair

Their daughter had brown hair like katniss and their son had blonde hair like peeta.

The daughter had dark hair and blue eyes and the son had blonde hair and grey eyes. You get it? They swapped Katniss and Peeta's hair and eyes! could you post a picof the drawing when it's done?!
