Chocolates have a tendency to fade badly, especially if exposed to sunlight. Sable Silver Martens are the variety least often seen at this time. The sables should be a medium sepia brown on the saddle, shading evenly down the sides to a lighter color. The ears, face, tail and outside of the feet and lower legs should be a very dark sepia brown, nearly black, providing a distinct contrast to the body color. Sables tend to become blotchy in color and also their body color usually continues to darken throughout their lifetime with each sucessive molt, reducing the contrast with the points.
