A look at sooty palomino horses around the world and on a variety of different breeds.
The sooty modifier causes dark hairs to grow interspersed throughout the coat, generally concentrated along the topline and points. This gene is much more obvious and dramatic on a lighter base and commonly found in animals with a cream dilution. Sooty palominos are the result of a cream dilution and a sooty gene on a chestnut base. This is the sooty combination that is perhaps most likely to change seasonally.
