11 de mar. de 2015 · Scientists in search of the key to chameleons’ incredible color-changing ability say they’ve found the answer: a lattice of nanocrystals beneath the lizards’ skin that reflect different...
20 de sept. de 2015 · For decades, biologists thought chameleons were able to change color using pigments in their skin. However, new research shows that pigments are only a small part of the process. To...
Chameleons change colour by dispersing 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.

19 de oct. de 2023 · New research suggests that the way chameleons change color is very different from what scientists had assumed. Join filmmaker and National Geographic Explorer Jason Jaacks as he explains how the color change is actually controlled by nanocrystals in a top layer of the lizards' skin.
19 de oct. de 2023 · A chameleon changes its color to adjust its body temperature to the outside temperature. They change color by changing the arrangement of certain skin cells called iridophores. These cells have nanocrystals that reflect light of different wavelengths, depending on their physical orientation.

Chameleon cells are different — iridophores can actually absorb or reflect any and all colors of the spectrum. "Some species change more colors than others," Flynn says. "For example, some will change shades lighter to darker, while others will change to more vibrant, bright colors.
10 de mar. de 2015 · The chameleon's uncanny ability to change color has long mystified people, but now the lizard's secret is out: Chameleons can rapidly change color by adjusting a layer of special cells...
