Selfs
Synonyms: Solid. These colors (save for white) are the base colors which other patterns and effects act on.
Black
Synonyms: Ebony. In solid black cats, the nose and paw-pads will also be black. Some black cats, especially longhairs, may have a reddish cast in the sun, or a brownish tone from sun exposure.

Chocolate
Synonyms: Chestnut. A dark brown cat. There is some variation in shade. The nose and paw-pads will also be chocolate.

Cinnamon
Synonyms: Sorrel (in Abyssinians/Somalis). A lighter reddish-brown, "the color of a cinnamon stick". Nose and paw-pads will be the same color or more pink.

Red
Synonyms: Orange, Yellow, Marmalade, Ginger. Anywhere from rich red-orange to a washed out yellow. The nose and paw-pads are pink or coral. "Solid" red cats are specifically bred to have low-contrast markings, since true solid red cats are not possible.

Blue
Synonyms: Grey. A grey cat, with a wide range of colors from pale blue-grey to deep slate. Nose and paw-pads are also blue, but may be darker than the coat.

Fawn
Synonyms: Beige. Lighter and warmer than lilac. Although it is ideally easy to distinguish from lilac, darker fawns can be difficult to identify. Nose and paw-pads are warm brownish-pink.

Cream
Pale yellow or tan, sometimes with a slight pinkish cast. Nose and paw-pads are pink. Like with red, cream cats cannot be solid, and any that appear solid simply have very low-contrast markings.

Caramel
Synonyms: Taupe. Caramel is a rare color caused by the action of the "dilute modifier" gene on blue, lilac, or fawn cats. It is a grey-brown, similar to lilac. "Taupe" specifically refers to lilac-based caramel.
Here is an example of a caramel cat.
Apricot
Apricot is caused by the same dilute modifier as caramel, but on cream. It is paler than ginger, but more saturated than cream. Because it is derived from cream, there are no true solid apricot cats.
Here is an example of an apricot cat.
White
Fully white cats have pink noses and paw-pads. White cats also have a higher incidence of heterochromia or "odd eyes", where each eye is a different color - usually one blue eye and one eye of another color.

Tortoiseshells
Synonyms: Tortie, Particolor. Tortoiseshells, typically only female, have patches of a "red" color, and a "black" color. The "red" color may display tabby markings even though the "black" color is solid.

Tabby Colors
Examples of each color of tabby. Red, cream, and apricot tabbies are not shown here because these cats are always tabbies, so examples can be found above.
Black Tabby
More commonly known as brown tabby. The background color may be almost black, light grey or brown, rich red-brown, or anything in between, but they can always be identified by their black stripes. The nose can be black or dark red rimmed with black.

Chocolate Tabby
Chocolate tabbies have a tan background color and chocolate markings. The nose can be chocolate or pinkish rimmed with chocolate.

Tortoiseshell Tabby
Synonyms: Torbie, Patched tabby. They have tabby markings across both colors. They come in every color of tortoiseshell.

Silver and Golden
The silver and golden series are caused by differing combinations of the silver gene, agouti and nonagouti, and wide banding.
Silver Tabby
Silver tabbies have a silvery background color and colored stripes. They come in every color and pattern of tabby.

Silver Shaded
Silver shaded cats are light silver ticked tabbies. The lightest of them may be referred to as silver tipped, because the hairs are tipped with color.

Smoke
The smoke pattern is caused by the silver gene acting on solid cats. Smoke cats have a silvery undercoat, best seen in longhaired cats.

"Smoke Tabby"
"Smoke tabbies" are not tabbies at all. They are smoke cats, usually shorthaired, who show faint tabby markings. This is especially common in kittens.

Golden
Golden tabbies have a bright golden background color and colored stripes. They come in every color and pattern of tabby, and in shaded and tipped varieties like silver.

Colorpoint Variants
Colorpoint and its related patterns are caused by temperature sensitive albinism, which causes less pigment to be produced in warmer areas of the body. They can combine with any other color or pattern.
Colorpoint
Colorpoint is known as the typical Siamese pattern, but it also appears in other breeds. Colorpoint cats have a light body, colored extremities, and blue eyes.

Mink
Mink is the signature pattern of the Tonkinese. Mink cats are darkly colored at the extremities, but the body is not as light as in colorpoint cats. They typically have green or blue-green eyes..

Sepia
Sepia is the pattern of the Burmese, and the darkest version of this pattern. Burmese cats have gold eyes by breed standard, but other eye colors are possible.

White Spotting
White spotting is the most common type of white markings in cats. It ranges from very small white markings to markings covering almost the entire body. White spotting can combine with any color and pattern. These are a few of the named patterns.
Mitts
Mitts or socks are one of the first areas of white to appear. There is also an allele that specifically causes white mitts found in the Birman breed.

Tuxedo
Tuxedo patterned cats have a white chest, partial or complete white muzzle, toes, and possibly a white tail-tip or white belly.

Bicolor
Bicolor is a term for (non-tortoiseshell) cats with roughly half white. It is sometimes used for a wider range of white spotting.

Mask and Mantle
Mask and mantle cats have two large masses of color - one on the head (the "mask), and one on the body (the "mantle").

Cap and Saddle
The cap and saddle pattern is similar to the mask and mantle, but each mass of color is smaller.

Harlequin
Harlequin cats have random spotting with a colored tail. Cats with random spotting and no colored tail are pied.

Van
Van patterned cats are white with colored splotches between the ears and a colored tail. The name comes from the Turkish Van, but the pattern appears in many breeds.

Calico
Also known as tricolors, calicos are tortoiseshells with over half white spotting. The patches tend to be larger and more distinct. Low-white tortoiseshells are more commonly called "tortoiseshell and white".

Point + White
I'm frequently asked If colorpoint and white spotting can combine, so here is an example. The combination of point and white patterns are frequently seen in Snowshoes and Ragdolls. This is a tortoiseshell point and white Ragdoll.

Breed Specific Colors & Patterns
Ruddy
Abyssinians and Somalis are bred to have a lot of red pigment, which gives them unique coloration. Black tabby becomes ruddy (also called usual or tawny), a rich red ticked with black. Cinnamon tabby is called sorrel, and is red with cinnamon ticking. Other colors do not change names, but all have distinct red or cream undertones.

Agouti Tabby
Agouti tabby is ticked tabby without banding on the legs, tail, and neck. It must be bred for, since it only appears in specific breeds.
Source: Heikki Siltala at catza.net
Sepia Agouti
The Singapura is unique in that it combines agouti tabby with the sepia pattern, resulting in dark ticking on an ivory background.
Source: Heikki Siltala at catza.net
Amber
Amber is a color particular to Norwegian Forest Cats. The cat is born a black-based tabby, then gradually lightens until they are similar in color to a ginger cat, possibly with some residual black pigment.

Nonagouti Amber
In non-tabbies, amber acts a bit differently. As they lighten, they retain dark stripes. They can also be identified by their dark noses.

Sunshine
Siberians have a special type of "golden tabby" known more specifically as sunshine. It is known to be distinct because silver sunshine cats, or bimetallics, have patches of silver and "golden".

Asian Leopard Cat Patterns
The following patterns can be found in breeds with ancestry in the Asian Leopard Cat, such as Bengals and Toygers. They arise from the combination of ALC genes with domestic cat genes.
Rosetted Tabby
Rosetted tabby is one of the two signature patterns of the Bengal breed. It varies widely in appearance, but the general pattern is spots with a dark border and lighter center.

Marbled Tabby
Marbled tabby is modified classic tabby. The pattern tends to be very rectangular, with lighter spots in the middle of the stripes.

Braided Tabby
Also known as "candle-flame" tabby, braided tabby is the pattern of the Toyger. It is a modification of mackerel tabby. The mackerel stripes tend to split longitudinally, with areas of medium darkness in between.

Charcoal
Charcoal is a Bengal trait that comes in two forms, "twilight" and "midnight". Both types have dark markings on the face and back, with those of midnight charcoals being darker than those of twilight charcoals. They also show reduced red pigment, though not to the same extent as silver cats.
"Twilight charcoal" and "midnight charcoal" were coined by Traipse Charcoal Bengals. They elaborate and show examples of each
