What color doesn't a cat have? - in detail
Cats exhibit a wide range of coat colors and patterns, influenced by genetics and selective breeding. However, there are certain colors that cats naturally cannot produce due to the absence of specific pigments in their genetic makeup. Cats lack the ability to produce pure green or blue pigments in their fur. While some cats may appear to have bluish or greenish hues in certain lighting or due to their coat’s texture, these are not true pigments but rather optical effects. Additionally, cats cannot naturally have fur that is entirely bright neon colors, such as fluorescent pink, orange, or yellow, as these colors are not biologically possible in feline genetics. The colors seen in cats are primarily variations of black, white, red (orange), gray, and brown, often combined in patterns like tabby, tortoiseshell, or calico. Any unnatural or vibrant colors observed in cats are typically the result of dyes or artificial alterations, not natural pigmentation.
