Male iguanas develop an orange to orange-red coloring as breeding season approaches. In some iguanas, the orange color may be diffuse over the entire body. In others, the orange can be concentrated in several areas including the dewlap, spikes, body, and legs. Female iguanas can also develop this orange coloration, though it is usually less intense.
Temperature can influence the color of an iguana. Iguanas tend to become darker if they are cold. The darker color helps them absorb more heat. In addition to the darker color, an iguana may develop dark, wavy lines on its head or body if it becomes chilled. Iguanas that are kept in too warm of an environment may become lighter.
Several weeks before shedding, an iguana's skin may appear dull and take on a gray or yellowish-gray cast. Unlike snakes, iguanas, and other lizards do not shed the skin over their entire surface at one time. White patches will appear where the skin loosens, just before being shed.
Iguanas with liver disease may appear yellow, especially their mucous membranes. This yellow color should not be confused with the yellow cast that may appear before shedding.
Bacterial infections of the skin, often termed "blister disease," "scale rot," or "vesicular dermatitis," can at first cause blisters of the skin, and then turn the skin a dark brown to black color. These infections are usually due to poor cage hygiene or too moist an environment. This disease can be fatal.
Young iguanas are generally brighter green or blue with some dark brown striping on the body and tail. The striping pattern of some results in a reticulated pattern. The dark patterns, striping, or banding on their bodies and tails become more intense as the iguana reaches approximately 18 months of age.

Hi! I’m Sreten Filipović. I graduated from the Faculty of Agriculture at the University of Belgrade, with a master's degree in Environmental Protection in Agricultural Systems. I’ve worked as a researcher at Finland's Natural Resources Institute (LUKE) on a project aimed at adapting south-western Finland to drought episodes. I founded a consulting agency in the field of environment and agriculture to help farmers who want to implement the principles of sustainability on their farms. I’m also a founding member of the nonprofit organization Ecogenesis from Belgrade whose main goal is non-formal education on the environment and ecology. In my spare time, I like to write blog posts about sustainability, the environment, animal farming, horticulture, and plant protection. I’ve also published several science-fiction short stories.
