Brown is a color. It can be considered a composite color, but it is mainly a darker shade of orange. In the CMYK color model used in printing and painting, brown is usually made by combining the colors orange and black. In the RGB color model used to project colors onto television screens and computer monitors, brown combines red and green.
Human hair color is the pigmentation of human hair follicles due to two types of melanin: eumelanin and pheomelanin. Generally, if more melanin is present, the color of the hair is darker; if less melanin is present, the hair is lighter. The tone of the hair is dependent on the ratio of black or brown eumelanin to yellow or red pheomelanin. Levels of melanin can vary over time causing a person's hair color to change, and it is possible to have hair follicles of more than one color on the same person. Some hair colors are associated with some ethnic groups due to observed higher frequency of particular hair color within their geographical region, e.g. straight dark hair amongst East Asians, Southeast Asians, Polynesians and Native Americans, a large variety of dark, fair, curly, straight, wavy and bushy hair amongst Europeans, West Asians and North Africans, curly, dark, and uniquely helical hair with Sub Saharan Africans, whilst gray, white or "silver" hair is often associated with age.
Sorrel is a reddish coat color in a horse lacking any black. It is a term that is usually synonymous with chestnut and one of the most common coat colors in horses. Some regions and breed registries distinguish it from chestnut, defining sorrel as a light, coppery shade, and chestnut as a browner shade. However, in terms of equine coat color genetics there is no known difference between sorrel and chestnut. Solid reddish-brown color is a base color of horses, caused by the recessive e gene.

Auburn hair is a human hair color, a variety of red hair, most commonly described as reddish-brown in color. Auburn hair ranges in shades from medium to dark. It can be found with a wide array of skin tones and eye colors. The chemical pigments that cause the coloration of auburn hair are frequently pheomelanin with high levels of eumelanin; however, the auburn hair is due to a mutated melanocortin 1 receptor gene in Northwestern European people and by a mutated TYRP1 gene in the Melanesians and Austronesians, both genes that reduce the melanin production of the hair cells.
Chestnut is a hair coat color of horses consisting of a reddish-to-brown coat with a mane and tail the same or lighter in color than the coat. Chestnut is characterized by the absolute absence of true black hairs. It is one of the most common horse coat colors, seen in almost every breed of horse.
Horses exhibit a diverse array of coat colors and distinctive markings. A specialized vocabulary has evolved to describe them.
Black is a hair coat color of horses in which the entire hair coat is black. Black is a relatively uncommon coat color, and it is not uncommon to mistake dark chestnuts or bays for black.
