Since it's only a yearling there could be a change of coat color going into it's second year. I've seen solid black apps quickly become roany apps with black spots. This baby may wind up a sooty buckskin which would show a light undercoat with a lot of dark shading since the sire is a cremello. I boarded a buckskin that altho pale yellow in mid summer, during the winter his legs would blacken right up to the body. His head and neck and shoulder winter hair would blacken as well but not as black as the legs. This made him look sooty. In spring as he started shedding his face and neck would take on a bronze shade. It was never the same two years in a row yet by summer he was always yellow with the usual black stockings almost to his knees.
