Given this reference on Yorkshire Terriers, tell me where they originate from, and what are their typical size and color.

Context:
The Yorkshire Terrier is a British breed of toy dog of terrier type. It is among the smallest of the terriers and indeed of all dog breeds, with a weight of no more than 3.2 kg. It originated in the nineteenth century in the English county of Yorkshire, for which it is named. Their coats are typically tan on the head with a dark steel-grey body, but they can come in a variety of colors.

It is a playful and energetic dog, usually kept as a companion dog. It has contributed to the development of other breeds including the Silky Terrier, and also to cross-breeds such as the Yorkipoo.<|im_end|>
