Swedishbrun

Swedishbrun is a coat color term used in some Swedish breeding contexts to describe a warm brown shade appearing in several domestic animals, notably dogs, cattle, and horses. The term is informal and not standardized in major breed registries. It is derived from the Swedish word brun meaning brown, with the modifier “Swedish” indicating origin or use within Sweden.

Appearance of Swedishbrun varies from light chestnut to dark chocolate, often with a reddish or mahogany undertone. In horses and cattle, the color may be accompanied by subtle markings or shading, while in dogs the shade may be solid or intermixed with small amounts of black edging on the muzzle or ears. Coat texture and length are species dependent and not inherent to the color designation alone.

Genetics of Swedishbrun are not tied to a single defined allele. It is generally regarded as a polygenic trait influenced by several pigment genes, including MC1R and ASIP, and modulated by additional modifiers. Outcomes can differ between species and lineages, and breeders may describe a range of brown tones under the same label.

History and usage: the term appears in various Swedish breeding literature and hobbyist registries as a descriptive designation for coats with a warm brown hue that does not fit more widely recognized color standards. It is not universally recognized or standardized by major breed organizations, and practitioners may use it differently across breeds and regions.
