The modern
Collie of both Roughcoat and Smoothcoat varieties are available in four distinct colors. Sable and White dogs are generally the most recognizable, the choice of the Lassie television and movie producers. The sable color on these dogs can range from a light blonde color to a deep reddish-brown, with any hue in between possible. Tri-Color dogs are mostly black and white with sable markings. Blue Merle collies are best described as Tri-Color dogs whose black has been diluted to a mottled gray-blue color. White collies are usually mostly white on the body with a head coloration of any of the three previous.
