What colors are not found in cats? - briefly
Cats do not have blue eyes naturally; any blue-eyed cat is likely to be a result of selective breeding or a genetic mutation. Additionally, cats do not typically display bright green or vibrant purple colors in their fur.
What colors are not found in cats? - in detail
Cats, much like other mammals, have a limited range of fur colors and patterns. The most common coat colors seen in cats include black, white, grey, brown, orange, cream, and various shades of these primary colors. However, there are several colors that are notably absent from the feline color palette.
One color conspicuously missing from cat fur is blue. While some breeds, such as the Russian Blue or British Blue, may appear to have a blue-gray coat, this coloration is not true blue but rather a dilution of black caused by a genetic mutation. True blue, as seen in birds like blue jays or peacocks, does not occur naturally in cats.
Similarly, purple and green are also absent from the cat's color spectrum. These colors are rarely found in mammalian fur due to the absence of specific pigments required for their production. Purple, for instance, would require a mix of red and blue pigments, neither of which is present in sufficient quantities in cat fur. Green, on the other hand, would necessitate a combination of yellow and blue pigments, which again are not naturally found in cats.
Another color notably absent from cats is pink. While some cats may have patches of skin that appear pink due to lack of pigmentation or thinning fur, this is not considered a true coat color. Pink as a fur color does not exist naturally in cats.
In summary, while cats exhibit a variety of beautiful and intricate patterns, their fur colors are limited primarily to shades of black, white, grey, brown, orange, and cream. Colors such as blue, purple, green, and pink are not found in cat fur due to the absence of specific pigments required for their production.
