Brookesia, Which Strips the Fake Green Coloured Coat

Chameleons exhibit color changes influenced by several factors. Primarily, they possess specialized cells called chromatophores that contain different pigments and can expand or contract to alter skin color. The guanophores retract the light on guanine crystal and ceeate additional color effects. Environmental factors such as temperature, light, and humidity also impact color expression, serving as camouflage or social signals. Emotional states, such as stress or aggression, can trigger rapid color shifts. Additionally, hormonal changes and health status play a role in determining coloration. This complex interplay allows chameleons to adapt their skin color for communication, thermoregulation, and protection, showcasing their remarkable ability to respond to their surroundings.

Chameleon skin color can also be influenced by external factors that are not directly related to physiological processes. Physical contamination, such as the accumulation of dirt from red laterite soil in dry regions or the presence of symbiotic algae, can affect the coloration of their skin. This superficial layer of coloration can be shed, revealing the chameleon's natural hues underneath. For instance, when a chameleon loses its outer layer contaminated with soil or algae, it may transition from a reddish or greenish to a more natural tone. Thus, external environmental elements play also a significant role in the appearance of these fascinating reptiles.
