The word "points" is given to the mane, tail, lower legs, and ear rims with respect to horse coloration. The overall name given to a horse coat color depends on the color of both the points and the body. For example, bay horses have a reddish-brown body with black points. [3] Point coloration is most often produced by the action of the agouti gene.
The third type is the xanthophores which contains yellow pigments in the forms of carotenoids. The various colors are made by the combination of the different layers of the chromatophores. These cells are usually located beneath the skin or scale the animals. There are two categories of colors generated by the cell – biochromes and ...
Before domestication, horses are thought to have had these coat colors. [1] Equine coat color genetics determine a horse's coat color. Many colors are possible, but all variations are produced by changes in only a few genes. Bay is the most common color of horse, [2] followed by black and chestnut.
Amphibians such as frogs have three kinds of star-shaped chromatophore cells in separate layers of their skin. The top layer contains ' xanthophores ' with orange, red, or yellow pigments; the middle layer contains ' iridophores ' with a silvery light-reflecting pigment; while the bottom layer contains ' melanophores ' with dark melanin.
Chromatophores are cells that produce color, of which many types are pigment-containing cells, or groups of cells, found in a wide range of animals including amphibians, fish, reptiles, crustaceans and cephalopods. Mammals and birds, in contrast, have a class of cells called melanocytes for coloration.
The brilliant iridescent colors of the peacock's tail feathers are created by structural coloration, as first noted by Isaac Newton and Robert Hooke.. Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination ...
