There isn't a perfect answer to this question because it would depend on what breeds make up your Palomino that you have in mind. That being said, Palominos are generally accepted as being gentle, calm, and easy to train. But remember, if your Palomino descends from a line of thoroughbreds, then you could have a more excitable and headstrong horse on your hands. However, experts will generally agree that Palominos primarily descend from Quarter horses. Now, if we assume that to be true for all Palominos, then you can expect your Palomino to have similar calm gentleness in their nature as is true for Quarter horses.
