Magic horses

Silver Orlov trotter stallion Caliostro.

I suspect it's not silver gene but gray-ing out. Many Orlovs gray out starting from mane and tail. But still... My favorite breed and favorite color. *_*

UPD. In the comments to the photo on the original site said that his dam's brown with silver-ish mane and tail and his sire's bay. Also there are speculation that he may be a Tori-cross, though this is unlikely.
