‘Silver’, ‘charcoal’, and ‘champagne’ are not recognised as colours existing in the Labrador Retriever.
The only recognised colours are black, yellow, and chocolate.
The original St. John dogs, brought from New Foundland to England in the early 1800s, were black, and to improve the breed several other breeds were introduced, like Golden Retriever, Chesapeake Bay Retriever, and Flatcoat Retriever.
Although black has been the favorite colour for many decades, yellows were accepted in the early 1900s.
