Silver dilutes the black pigment on the body of the horse to a silvery chocolate color, and turns the mane and tail flaxen. This means that black horses show the effect most strongly. Bay horses have their black legs diluted and flaxen mane and tail, but their red body remains unchanged. Because they do not have black hair to dilute, chestnut horses that have the silver dilution do not show the effect. Because chestnuts with the silver dilution can have self-colored manes and tails, it does not appear that silver alters their manes and tails to flaxen. 

Silver-diluted black can vary in color from a pale taupe to a deep chocolate that approaches black. Seasonal changes are common, with winter coats tending to be paler. As they age, the flaxen manes and tails tend to darken, starting at the roots. Black silvers sometimes show dappling. This is especially vivid when the horse is clipped. Paler silvers sometimes have a dark face mask similar to that seen on dun horses. 

When combined with cream, silver-diluted black pigment tends to lose its cool, silvery tones and look more like milk chocolate. Black silvers with cream, sometimes called silver smokies, often lack the contrast in their manes and tails seen in ordinary black silvers. 

 

Champagnes have dusky pink skin with dark freckles (left) and amber eyes (above).

Champagne horses sometimes have reversed dappling, which can mimic the pattern seen on ordinary dappled horses in reverse.

Silver is caused by a mutation to the PMEL17 gene, also known as SILV. Commercial tests to identify silver horses are available. Research on ancient remains suggest that the mutation dates back to at least to the Iron Age. 

The mutation for silver is associated with Multiple Congenital Ocular Anomalies (MCOA), formerly known as Anterior Segment Dysgenesis (ASD). Homozygous silvers are believed to be at higher risk for these eye defects.

There are four breeds where silver is common: American Shetlands, American Miniatures, Rocky Mountain Horses and Comtois.

 

Silver is found more rarely across a wide range of breeds. Among the American breeds it is found in the Morgan, Tennessee Walking Horse, Missouri Foxtrotter, Saddlebred, Quarter Horse, Banker Ponies and the Mountain Pleasure breeds. Among the British native breeds it is found in Welsh Mountain Ponies, Highland Ponies, Gypsy Horses and the Shetland Pony. Other breeds include the Australian Ponies, Australian Stock Horses, Dutch Warmbloods, Dutch Harness Horses, Finnhorses, German Classic Ponies, Icelandics, Nordlands, and Estonian Natives. 

Here are links to some examples of silver horses of various breeds. Be aware that links to individual horses can and do change. If a link no longer works, try searching on the name and breed.
