Cat color and patterns

Colors: Black, chocolate, blue, lilac, fawn, red, cream, white. See pictures and details here: Solid Cat Coats. As expected, solid color means continuous color. It is not unusual, however, for faint tabby markings to show through, particularly for cream (dilute red) and red cats. The cats featured are black and blue (Nox and Sky – Ken & Helmi’s cats). 1
Mosaic of color pigment; eumelanin and phaeomelanin. The amounts are determined at the embryo stage. Colors: chocolate, cinnamon, blue, lilac or fawn tortie (the last 3 are diluted). The preferred pattern is evenly distributed with good delineation between the colors. The nose streak (blaze) is desired. Tortoiseshell cats, Black Tortoiseshell cats. 2
Tabby – mackerel is one type
The most commonly encountered cat color and pattern. See much more here: Cats coats tabby. There are two things going on to make the tabby pattern: the famous agouti gene producing the ticked (banded) hair shafts and the Primary Tabby gene. Patterns: ticked, mackerel, spotted classic and marbled.
Tipped – black smoke is one type
This cat color and pattern relates to the fact that the individual hairs are colored at the end, the tip.The lower portion of each individual hair shaft lacks color color due to the inhibitor gene and it is thought, another gene. The amount of the tipping dictates the type either, smoke, shaded or chinchilla. See-Black Smoke Maine Coon
Silver – spotted is one type
The ground color has been “silvered”. It is caused by the inhibitor gene that removes the yellow pigment granules in the hair shafts. The smoke effect above is also caused by this gene but in the case of smoke the yellow pigment in the hair is removed from the lower part only. Examples: chinchilla, spotted tabby, silver torbies.
We all know the Siamese and the pointed coat. Pointing means that the “points” of the body (i.e. extremities, the mask, ears, tail and feet) are darker. There are many variations of pointing, which can be seen here: Cat Coats Pointed.The cat on the left is a Modern Siamese with the classic seal pointing. 6
Solid & White
The Solid and White cat is a solid colored cat with the white spotting or piebald geneproducing the white areas by preventing the migration of the pigment cells during the embryonic stage.The cat on the left is a black and white Cornish Rex.See: Cat Coats Solid and White 7
Tortoiseshell & White
These are called Calico cats in the USA and as a less technical term in the UK and elsewhere. Tortoiseshell and White cats are, as expected, the result of the presence of the genes that produce the tortie mosaic together with the white spotting genementioned above.This post covers it all: Calico Cats. 8
Tabby & White
One sees lots of tabby and white cats because they are so popular. The coat color and pattern is caused by the well know piebald or white spotting gene interacting with the genes that produce the tabby pattern, the Primary Tabby gene. This page deals with this coat color and pattern in more detail: Cat Coats Tabby and White. 9
Tipped & White – golden shaded
Golden shaded and white is just one example of a tipped cat color and pattern. The cat illustrated is a golden shaded Australian Tiffanie cat called Gastonne.Tipping, as mentioned, is caused by the inhibitor gene. The white areas are caused by the piebald gene.10
Silver & White
I have already mentioned the silver coat color and how it is formed. In the silver and white cat color and pattern (and curled hair!) the silvered hair is affected once again by the piebald geneto create the white areas.The featured cat is a silver laPerm, one of cat breeds with curly cat coats.
Pointed & White
You can see how the points, the extremities of this Snowshoe cat have been rendered white by the white spotting or piebald gene.See: Cat Coats Pointed for a discussion on the genetics of pointing and this page: Snowshoe cat for more of this very interesting looking cat.
