Like much of coat color genetics, commonly used terms do not necessarily correspond to precise genetic states. Nevertheless, terminology can reveal a lot about the genetic interactions surrounding the leopard complex. The reddish leopard-spots in this otherwise bay coat are only visible after leopard-related roaning has occurred, as here.
Roan is a coat color found in many animals, including horses, cattle, antelope, cats and dogs. It is defined generally as an even mixture of white and pigmented hairs that do not "gray out" or fade as the animal ages. [1] There are a variety of genetic conditions which produce the colors described as "roan" in various species. Bay Roan with ...

A single copy of the allele has minimal impact on eye color, but when two copies are present, a horse will be blue-eyed in addition to a light coat color. The cream gene is one of several hypomelanism or dilution genes identified in horses. Therefore, it is not always possible to tell by color alone whether the C Cr allele is present without a ...
Equine coat color genetics discusses color genes in horses, including a brief description of dilution genes; Equine coat color describes various colors in horses; Cream gene, describes the process for horses by which the cremello, perlino, smoky cream double-dilute colors are created as well as the buckskin, palomino and smoky black single ...
The silver or silver dapple (Z) gene is a dilution gene that affects the black base coat color and is associated with Multiple Congenital Ocular Abnormalities. It will typically dilute a black mane and tail to a silvery gray or flaxen color, and a black body to a chocolaty brown, sometimes with dapples. [1]
Chameleons - Colour change signals a chameleon's physiological condition and intentions to other chameleons. [3] [4] Because chameleons are ectothermic, they change color also to regulate their body temperatures, either to a darker color to absorb light and heat to raise their temperature, or to a lighter color to reflect light and heat, thereby either stabilizing or lowering their body ...
Tobiano is a spotted color pattern commonly seen in pinto horses, produced by a dominant gene. The tobiano gene produces white-haired, pink-skinned patches on a base coat color. The coloration is almost always present from birth and does not change throughout the horse's lifetime, unless the horse also carries the gray gene.
