Chameleon skin is filled with these tiny crystals and when they move their skin by relaxing or tensing up their bodies the crystals shift and reflect light differently. The skin cells also swell and shrink so that they move closer and farther apart.
Shorter wavelengths of light, such as blue, are reflected when skin is relaxed, and the iridophore cells are close to each other. Since chameleon skin also contains yellow pigments, the blue and yellow colors mix to create a color we often see in chameleons at rest - green. Longer wavelengths of light, including red and yellow, are reflected when skin cells are farther apart.
Research also found that female chameleons have far fewer iridophore cells in their upper skin layer making males able to change color better than females. Blending into their environment is the top reason why chameleons will change colors so that they can camouflage themselves and escape predators. But camouflage isn't the only reason to alter an appearance. Scaring away rival chameleons, impressing mates, stress, conserving heat and staying cool are all potential reasons for dramatic color changes.
Chameleons brought into seeing the vet may turn dark colors or black due to stress, while happy and relaxed chameleons will be bright green and blue at home. Some chameleons can turn more colors than others, but all chameleons possess some amount of iridophore cells in their skin. Chameleons, like many other pet lizards , are amazing creatures!

These colors are more in line with the colors of leaves, foliage, and trees where the chameleon will try to hide in. When this information is received, the brain automatically tells the body to release melanin in the skin, which alters the nanocrystal structure in the outer layer of the skin.
If the chameleon needs to relax or cool down, the nanocrystals change again to allow different colors. This may also be used to communicate with other chameleons certain information such as when the female is willing or unwilling to mate.
As discussed above, most scientists believe the camouflaging effect is coincidental to the color-changing purpose of regulating the body and expressing a mood. For more on how chameleons react to stress, read about why chameleons hiss.

While some chameleons will stick almost entirely to green and brown, there are some with a wide variety of hues which show in mesmerizing ways. This is thought to be due to their isolated and colorful environments, which, over time, have developed variety through evolutionary pressures.
