Hair color lol

Okay so weird post maybe. But I’ve always wanted a dark hair kid.... I HAVE dark hair and just always thought my daughter would to. But I have a blonde/blue son and a blonde/hazel daughter. This is my third child will he/she be blonde to?? Father is dark blonde I’m brown. I know it’s only predictions but 50% chance of brown hair but two blondes lol. Feel like my luck is slim. (Yes I love my kids either way!)
