If you’ve studied cats for very long, you probably know that calico and tortoiseshell cats - those with both black and red coat colors - are female. These inherited polygenes are controlled through selective breeding in pedigreed breeds. Polygenes, genes that require multiple others of their kind for their effects to be observable, then determine whether the coat color tone will be a dark steel gray-blue or a pale powder blue, she explains. “The hundreds of colors and patterns displayed in domestic cat coats come about because of modifying factors that include both genes and polygenes, which change these basic two colors,” she says, giving an example of the dilute gene, which changes cat colors from black to blue (commonly called gray) and red to cream. By red, we mean what is commonly called orange. Cat colors - what coat colors can cats have?īasically, when it comes to cat colors, cats are black unless they have inherited the sex-linked orange masking gene, in which case, they are red, Miller explains. Cats basically come in black, red, white or some combination, dilution or mixture of these.
“Birds derive their brilliant coloring because of the chemical structure of their feathers and amino acid modifiers, which is different from that of cat coat textures where pigmentation is based on melanin types,” says Joan Miller, the Cat Fanciers’ Association’s outreach and education chair and renowned cat expert.
