Animal colouration is the general appearance of an animal resulting from the reflection or emission of light from its surfaces. Some animals are brightly coloured, while others are hard to see. In some species, such as the peafowl, the male has strong patterns, conspicuous colours and is iridescent, while the female is far less visible.
Anoles - The majority of anoles ( Dactyloidae) can change their color depending on things like emotions (for example, aggression or stress), activity level, levels of light and as a social signal (for example, displaying dominance ). Frogs, e.g. gray treefrog and Peron's tree frog (which can change colour in less than one hour).

Zooarchaeology has identified three classes of animal domesticates: Pets ( dogs, cats, ferrets, hamsters, etc.) Livestock ( cattle, sheep, pigs, goats, etc.)

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.
The tapetum lucidum ( Latin for 'bright tapestry, coverlet'; / təˈpiːtəm ˈluːsɪdəm / tə-PEE-təm LOO-sih-dəm; pl.: tapeta lucida) [ 1] is a layer of tissue in the eye of many vertebrates and some other animals.
