Jun 27, 2024 ·"Thecolorchangeyou are seeing is based on structural changes of crystal-like cells called iridophores underneath the skin that refract light, Flynn says. When anything agitates or exhilarates thechameleon, things start to get interesting. Chameleons change colour bydispersing or concentrating pigment granules(melanophore cells) in the cells that contain them.
In general, the animal appears lighter-coloured when pigment is concentrated and dark when pigment is dispersed throughout the cells.Nov 25, 2025 ·The popular belief that chameleons change color primarily to blend into any background is largely a misconception. While camouflage plays a role, the most frequent and dramatic color shifts serve two other main functions:social signaling and thermoregulation.Jul 22, 2025 ·Chameleons change color primarily forcommunication and temperature regulation, not just camouflage. They utilize specialized cells called chromatophores containing pigment that they can expand or contract to alter their skin's appearance.In addition to being responsive to light, chameleons change colorwhen they are frightened and in response to temperature and other environmental changes.
Hormones that affect special pigment-bearing cells in the skin cause the color change.View allAug 25, 2025 ·Discover the science ofchameleoncolorchange.

Its color does not always change to match its surroundings, however, as is commonly believed. The changing colors of a chameleons skin are due mostly tospecial pigment-containing cells in its skin, although some of the color is due to an effect similar to what causes the daytime sky to be blue.

Learn about the key purposes of this remarkable adaptation in their survival. The melanin in the melanophores is able to condense and move up to darken the chameleon’s color, or disperse and move down to lighten it. Iridophores are cells that contain nanocrystals: these are transparent and made up of guanine, one of the four bases that make up DNA.
The nanocrystals form a lattice which can become more loosely or densely packed as the nanocrystals move towards or away from each other. March 1, 2019 -Chameleons change colourby changing the space between the guanine crystals, which changes the wavelength of light reflected off the crystals which changes the colour of the skin. New research suggests that the ...
