I am not 100% sure if this is a palomino but I just love the picture.
I know that this is not a "true" palomino color but I have read that palomino is not a breed of horse, and never could be, because the palomino color does not breed true.
A palomino is heterozygous-- meaning it has only one cream gene-- so two that are crossed have a 25% of producing an offspring with no cream genes (a red chestnut), 25% of producing an offspring with two cream genes (a cremello), and 50% chance of producing another palomino (one cream gene).
On the other hand, crossing a cremello with a chestnut gives 100% palomino foals. So when I look at the foal I would argue the case.
The horse is one of two extant subspecies of ''Equus ferus''. It is an odd-toed ungulate mammal belonging to the taxonomic family Equidae. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature into the large, single-toed animal of today. Humans began to domesticate horses around 4000 BC, and their domestication is believed to have been widespread by 3000 BC. Horses in the subspecies ''caballus'' are domesticated, although some domesticated populations live.. more
