I can see it, and yes, it is possible.
Pangare is when a horse has lighter underparts. It's most common on chestnuts, and I bet you would recognise a very familiar breed that almost always has it. That is the Haflinger.
Can you see the way the coat is lighter in the underparts? Mostly legs, elbow, under the hindlegs, the belly, even up the base of the neck and on the head. Genetically this horse is chestnut
