![]() Fawn is the dilute form of Cinnamon it is described as “coffee and cream” or caramel color. Lilac is the dilute form of Chocolate it is described as dove or light taupe gray, and is sometimes called frost or lavender. Blue is the dilute form of Black it is commonly seen as various shades of gray. These colors are due to clustering of the particles of pigment in the hair shaft. These are alleles at the (B) locus Chocolate is recessive to Black, and Cinnamon is recessive to Chocolate.Ī mutation of the gene for Dense coloration produces Blue, Lilac, and Fawn. Cinnamon is a terra-cotta or burnt sienna color. The Chocolate color is a medium to dark brown color it is sometimes called chestnut. These colors are thought to be due to a smaller number of eumelanin granules in the hair shaft. ![]() Mutations of the gene for Black give rise to Chocolate and Cinnamon. The following table lists the commonly accepted names for the basic colors, by genotype: The most variation is found in the black-based (eumelanistic) colors. Several genes can cause variation in the density of the the melanin granules, so other colors can be produced. Phaeomelanin granules are thought to be elongated “footballs” in shape, and reflect light in the red-orange-yellow range. Eumelanin granules are thought to be spherical in shape and absorb almost all light, giving black pigmentation. There are two chemically different kinds of melanin: eumelanin and phaeomelanin. Melanin is deposited in the hair shafts in the form of microscopic granules which vary in shape, size, and arrangement, giving a variety of colors. The colors in hair, skin, and eyes are caused by the presence of melanin. It does not attempt to explain the mechanisms of inheritance nor the formulas for calculating the possible outcomes of particular breedings. This article attempts to introduce and describe the colors and patterns of domestic cats and the names that are given to them. Many people have expressed confusion over the names that cat fanciers apply to the coat colors and patterns, so this article has been written to help explain the names given to the possible colors and patterns, and why these names are applied. The names given to these colors and patterns are increasingly based on genetic theory. You may want to read section A first to become familiar with cat color terminology.ĭomestic cats exhibit a rich variety of coat patterns and colors. If you are interested in the genetics of different colors and in what colors are theoretically possible, read section B. If you want to read about which colors are commonly seen in cats, or if you want to know what your cat’s color is called, read section A.
