The eyes of the Weimaraner may be light amber, grey or blue-grey. 2.1.1 Coat and color. This breed's short coat and unusual eyes give it a distinctive regal appearance. The coat is extremely low-maintenance, short, hard, and smooth to the touch, and may range from charcoal-blue to mouse-grey to silver-grey or even blue-grey. Where the fur is thin or non-existent, inside the ears or on the lips for example, the skin should be pinkish rather than white or black. This breed does not have an undercoat, so extreme cold should be avoided. While their coat is short, this breed does shed. The Weimaraner's coat color led to its nickname of 'the Grey Ghost'.
