1. Tables for coat colors, patterns and colors of admitted eyes.
The Norwegian Forest have a number of colors and patterns recognized, ie may have on their mantle some colors and patterns, but if it appears a different color or a unrecognized pattern, we will certainly be faced with a mixture with another breed and can not we talk of a Norwegian Forest purebred, never get their pedigree, or it is a genetic mutation.

|Solid (not shown)||Tabby|
|Solid (not shown)||Tabby|
- Amber tabby: The kitten is usually born with black tabby pattern. Its pads are pink. The regions between the stripes are from orange to brown. Therefore, some have the appearance of tortoises and others appear as black tabby kittensdepending on how much amber have at birth. They are acquiring the color as they grow, even some not having the color until adulthood. When acquire amber black tabby markings have been clarified in a variable manner, the tone goes from orange-brown to cinnamon. The color between those dark stripes is apricot. The nose is pink with no outline, the pads are dark, like the eye area.
- Solid amber: The kitten is usually born with black tabby pattern, their pads and nose are dark, because has dark skin like solid. It presents a very marked tabby, to the extent of being mistaken for a black tabby cat. The dark color becomes lighter little by little, in the same manner as in tabby cats. The original color is only identifiable to the level of the nose, the tail, the back and the tip of the legs. Its color lightens slower than tabby amber. Color coat is apricot and cinnamon. The ghosts marks remain until the mantle sufficiently clear, but sometimes may have high residual contrast. The nose pads and remain obscure.

Ámbar Light (Diluido):
- Amber Light Tabby: The kitten is born with a blue tabby pattern. Their pads are pink, and the regions between the black stripes can be from beige to light blue. Some seem blue-cream tortoise and others appear blue tabby kittens. According grows, blue tabby markings are clarified, as are the regions between the stripes. This will be seen more clearly if the kitten looks blue tabby at birth. The original color will be identifiable to the level of the tail, the back and the tip of the legs and ears. The pads are dark. They are acquiring the color as they grow, even some not having the color until adulthood. When it has acquired absolutely clear amber color, color tabby pattern is pink beige to cinnamon. Between stripes color is beige. The nose is pink with no outline, the pads are dark and the eye area.
- Solid Amber Light: The kitten is born blue, their pads and nose are dark. It presents steep tabby markings, to the extent that it can be confused with a tabby kitten. As it grows, and blue is clear to give a light amber. The original color is only identifiable to the level of the nose, the tail, the back, the tip of the legs and ears. The color lightens more slowly than in amber tabby diluted. As an adult, the robe is pinkish beige to cinnamon. The ghost marks persist until the mantle is clear enough, although it may have a marked residual tabby. The nose pads and remain obscure.
- Tabby Undefined: (EMS Code 21), is as plus tabby cat has the gene of white spot (S) in its expression Harlequin (02) and Van (01) and showing tabby drawing is not enough to know what is the corresponds tabby.
5. Inhibitor color (Silver or Smoke) and "Gen Chinchilla"
It is not just a color, but are two genetics factors, one is dominant, the "I", which inhibits or alters the production of melanin from the hair shaft, one white part or grayish and the rest of the color of the cat , getting your cat in silver and "cold" display. Depending on whether the cat is striped or solid is called differently. For cats tabbies (scratched) is called Silver (Silver) while for solids is Smoke.

|Genotypic and phenotypic hypothetical representation as how it affects the "Wb" to hair coloring, combined or not with the "A" (or agouti tabby), "a" (solid), with inhibitor "I" without inhibitor alleles "i '|
|Golden Shaded||Golden Shell|
6. Dominant White:
The eyes of cats have the gene for white W can have yellow eyes, copper (or orange), green or blue, and also have one of each color (in all combinations of above colors), which is known as "odd eyes" (EMS Code 63).
7. White spoting:
- White Unspecified (EMS Code 09): It is an unspecified amount of white, it may appear on the face, head, legs, belly, chest ..., always less than 50% of the cat.
- White Bicolor (EMS Code 03): 50% of the color of the cat is white and the other half has its color.
- White Harlequin (EMS Code 02): The white color in the cat is between 60% and 80%, small colored spots appear on his head, tail, legs and back.
- White Van (EMS Code 01): When the cat is white in more than 80%, and is only colored head and tail mainly.
And these are the colors and patterns that can be found in the Norwegian Forest cats.
8. Eye color:
Both in one color:
|EMS: 61||EMS: 62||EMS: 64|
|Odd eyes with Blue|
Eyes Odd other colors (without Blue), such Eyes Odd more rarely.
