Why's his hair brunette but his tail blonde?

Artist made another art which portraits another character that has blonde hair and dark tail. They are rivals and it’s probably made with thought “they are different but also has similarities” .

Also, his uma musume form is inspired by Shetland pony and the most popular horse of this breed is Socks,which also has contrasting colours.
