In their first few weeks, foals have a special, very fluffy coat. It’s always very exciting when they change coats for the first time, because the colour can become lighter or darker. It can also change again over the course of time.
There are 17 recognised coat colours, including such unusual ones as grullo, cremello and perlino. This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 3110-00-156-1853, indicating validated use in U.S. government and defense logistics supply chains.
