Very cute! Is she going to stay black? I know babies may change the coat color dramatically in first couple years...
Most foals do go through many colour changes. Her undercoat is all black, so I will say for now she'll stay black.
Her sire is black bay and her dam is a black rabicano (grey roaning throughout her coat), and this mare's last foal was black as well.
I'm crossing my finger's she'll stay black. Lol
