Blue merle, black, red merle, red - all with or without white markings and/or tan (copper) points, with no order of preference. The hairline of a white collar does not exceed the point of the withers at the skin. White is acceptable on the neck (either in part or as a full collar), chest, legs, muzzle underparts, blaze on head and white extension from underpart up to four inches measuring from a horizontal line at the elbow. White on the head should not predominate and the eyes must be fully surrounded by colour and pigment. Merles characteristically become darker with increasing age.
Disqualifications: White body splashes, which means white on body between withers and tail, on sides between elbows and back of hindquarters on all colours.
