pelsfarge

Pelsfarge describes the coloration of the fur (pelage) on mammals, especially species valued for their pelts. It encompasses hue, brightness, and pattern, with uniformity and luster often important in assessment. In zoology, pelage color is determined by pigments in the hair shaft, primarily eumelanin (black/brown) and pheomelanin (red/yellow), and by genetic factors that regulate pigment production, distribution, and hair growth. Many species exhibit multiple alleles and modifiers that produce a range of natural colors, including solid, spotted, banded, or tipped patterns. Seasonal and developmental changes can alter pelage color; molts replace old fur with new, and some species undergo color shifts, for example arctic foxes becoming white in winter.

In the fur trade and breeding programs, pelts are graded by color uniformity, intensity, and the absence of discoloration or staining. Common categories include solid (uniform) colors and various patterns such as agouti or tipped varieties. Color genetics and selective breeding are used to stabilize desirable pelage colors in farmed species like mink, fox, and rabbit.

Variation in pelage color is widespread across taxa and populations, with numerous named colors in both commercial breeds and wild species. Some color variants may arise from mutations or environmental influences such as diet and sun exposure, although genetics typically plays the dominant role.

Ethical considerations, animal welfare regulations, and labeling requirements influence contemporary trade in pelts and information about pelage color.
