Iguanas might be changing colors when they feel cold or hot, when they are stressed, sick, shedding, during the mating season and more. Changing skin color helps iguanas dominate or perform bodily functions more efficiently.

  1. Before shedding, specific spots that are getting ready to shed will be becoming milky white in color. Iguanas shed every 4-5 weeks, but babies and juveniles – more often.
  2. If your iguana got burnt, its skin will turn bluish and black, and then will dry and become dark brown to black. Straight after the burn, the skin might also look pink and lose all the scales.
  3. Males will become very bright orange during the breeding season, especially alpha males. Females tend to become orange as well, but not as bright. The orange coloring might stay for longer than few months, as well. Some iguanas also tend to get some orange coloration with age.
  4. Genetics. There are genetic variations of iguana coloration, some can be yellow, reddish, grey and some more turquoise. These iguanas are also bred selectively to have these colors (morphs) – the colors will become more prominent with age. Belly is usually the last to drop the green color. However, some baby colors might also disappear with age (such as turquoise on the back or around the head).

  • Your iguana is getting older. All green iguanas tend to turn dark green with age. Baby iguanas are very bright green, but they often get more brown through the years. Some iguanas tend to become orange-brown already by the age of 1.5-2 years. Don’t forget that older iguanas will also develop stripes, zigzags and other markings.
  • Low temperatures. Iguanas tend to get darker quickly when they get cold, because this will attract more heat. The dark coloration passes once iguana is warm again. Very hot iguanas become light in color.
  • Stress. Iguanas tend to get darker when they are stressed. Some will have their stripes get darker, not the whole body. In iguanas, stress can be caused due to lack of supplies in the tank, small cage, other lizards or pets, improper diet and more.
