Liver (color)

Liver is certain types of dark brown color in dogs and horses.

In dogs, it is a dark brown shade.

In horses, liver chestnut is a chocolate-colored chestnut horse. A liver chestnut is the same genetically as a regular chestnut, but the shade is a dark brown rather than the reddish or rust color more typical of chestnut. A horse that appears to be a liver chestnut but has a light colored mane and tail, sometimes colloquially called a "chocolate palomino," could be a horse manifesting the champagne gene. However, "flaxen" or light-colored manes and tails are also seen in chestnuts.
