Dreaming about chameleon talks of your capacity to change just like every chameleon does by changing their color and be adaptive to the uncertain and even the unpredictable things in your life. Such a dream means that no matter what happens, you would surely remain strong and adapt to the situation. You may be curious about how Chameleon changes their color.

Before going into "how" we should first take a dip into "why". Why Chameleon changes color?

It's a common misconception that they do this to camouflage themselves against a background. In fact, chameleons mostly change color to regulate their temperatures or to communicate with other chameleons.

Since chameleons can't generate their own body heat, changing the color of their skin is a way to maintain a favorable body temperature. Changing color works as a kind of external thermostat. A cold chameleon may become dark to absorb more heat, whereas a hotter chameleon may turn pale to reflect the sun's heat.

Chameleons will also use bold color changes to communicate. Males become bright when they're attempting to express their dominance and turn dark in aggressive encounters. Females use their skin color to signal a willingness or lack of willingness to mate. So, On the basis of color of its skin One can easily learn to read their chameleon's mood .

Now since we are done with "why" part lets hit the "how" part.

The outermost layer of the chameleon's skin is transparent. Beneath this are several more layers of skin that contain specialized cells called chromatophores. The chromatophores at each level are filled with sacs of different kinds of pigment. The deepest layer contains melanophores, which are filled with brown melanin (the same pigment that gives human skin its many shades). Atop that layer are cells called iridophores, which have a blue pigment that reflects blue and white light. Layered on top of those cells are the xanthophores and erythrophores, which contain yellow and red pigments, respectively.

Normally, the pigments are locked away inside tiny sacs within the cells. But when a chameleon experiences changes in body temperature or mood, its nervous system tells specific chromatophores to expand or contract. This changes the color of the cell. By varying the activity of the different chromatophores in all the layers of the skin, the chameleon can produce a whole variety of colors and patterns.

For instance, an excited chameleon might turn red by fully expanding all his erythrophores, blocking out the other colors beneath them. A calm chameleon, on the other hand, might turn green by contracting his erythrophores and allowing some of the blue-reflected light from his iridophores to mix with his layer of somewhat contracted yellow xanthophores.

With these layers of cells, some chameleons are capable of producing a dazzling array of reds, pinks, yellows, blues, greens, and browns. These bold statements won't help them blend into the background, but they will allow them to get their message across to other chameleons loud and clear.
