Chestnut agouti fur –notice the various hair colors and dark ticking. “Tan Pattern”. Dominant over self pattern, recessive to agouti pattern. Tan patterned colors have a solid top color over the back, with lighter markings of silver, cream, or red—like on the tan breed. Tan pattern markings are found everywhere that agouti markings are found.. Tans have a triangle of marking color at the nape of the neck. Tans may show some lighter ticking up the sides, but not over the back. Tans never have ring color. Includes any variety with otter or marten in its name. Many tan pattern varieties are not recognized, like seal marten. Ring Color: Having 3 to 5 bands of color on a single hair. Usually has dark base, white or yellowish intermediate color and dark tip. Rings of color are seen when coat is blown into. Not to be confused with a faded undercolor in self or tan pattern varieties. Ticking: having guard hairs of a different color than rest of coat. Undercolor: Color of the fur at the base of the hair, next to the skin. “Self Pattern”. Recessive to other two genes, thus cannot carry A or at. Self pattern colors may have shading, but they will not have agouti or tan pattern markings. Undercolor may fade next to the skin but generally each hair is a single color. Examples include but are not limited to black, blue, chocolate, lilac, Siamese sable, smoke pearl, seal, tortoise, and pointed white. A pure white is not necessarily a self. Black Silver Marten (A tan pattern color) ~Putting them all together~ All rabbit colors have a black, blue, chocolate, or lilac base. Also, all colors have one of three patterns: either agouti pattern, tan pattern, or self pattern. When we put them together, we get the colors shown in the table. You can see how the gene sets work together to form different varieties.
