Since there are so many colors of the Chihuahua dogs and a lot of owners wondering about all of these... let's try to sort out exactly what some of the colors actually mean:
Black Sable Fawn:
This Chi dog will be fawn with black sabling. Sable refers to black tips hairs. Therefore, the base color will be fawn and the tipping of the hairs will be black. This creates a textured appearance that is quite beautiful.
A full, solid black is very rare. Many black Chihuahua dogs will have some type of marking on the body.
This can range from a dark orange or a brown/orange and is often referred to as mahogany.
This is actually a pattern. It is a particular striping. Most brindle Chihuahuas are black over fawn....this will look similar to "tiger stripes".
This is a splashed pattern, usually with blue or black splashes. This color may carry through to the eyes as well. The gene that creates this, produces random dilutions to the coat of the Chihuahua. It is important to never breed two Merles together as it can produce puppies that have issues with sight and/or hearing and other health problems
Fawn & Gold:
What is the difference between fawn and gold? There is a lot of confusion with Chihuahua owners regarding this, so let's talk about the difference.
This is a light tan that may have an undertone of red.
Shinier than fawn, especially noticeable when the Chi is outside.
Blue is determined by skin color. The coat may appear to be any shade or variance of black. It is the skin pigmentation that classifies a Chihuahuas as blue; the paw pads, lips, eye rims and nose will be blue. For many Chihuahua, these areas may appear black, however under bright light (outdoor sunlight works well), there will be a noticeable bluish tint.
Blue & Tan:
Blue, as described above, with tan points, usually with tan tips on the paws. Some have tan around the ears and/or above the eyes.
Gray & Silver:
Many ask what the difference is between gray and silver on a dog. The element that makes silver, is that white slivers will slice through the gray coat, producing a color that is shinier than an otherwise standard gray.
