Chameleon.
The way chameleons change color is similar to how mixing different colors of paint creates new colors. In general, chameleons change color using chromatophores and melanin. Chromatophores are cells that contain pigment or color; These cells have two layers, with the upper layer containing red or yellow pigment and the lower layer containing blue or white pigment. Melanin, on the other hand, is essentially a substance that determines the darkening of skin color, and the presence of more melanin causes darker skin. When the autonomic nervous system (ANS), a part of the nervous system that controls involuntary body functions, tells cells to expand or shrink, the different colors mix like ink and change the color of a person’s skin. chameleon.
Chameleons change color in reaction to environmental changes and emotional stress.
Although chameleons have the ability to change color, some species have limits to the range of colors they can display. The same applies to the range of patterns they can display as well. In general, most chameleons can change between the colors green, black, and brown. Some chameleons can also change to a variety of other colors, with the most vibrant color changes usually appearing on males when they are looking and ready to mate.
While the purpose of some patterns is to help chameleons blend in with their surroundings, it’s a common misconception that chameleons change color for camouflage. This misconception is understandable, as chameleons can change color and look very much like their surroundings. For example, a chameleon with certain patterns and colors can be very well combined with a branch. In fact, however, chameleons change color in reaction to environmental factors such as light and temperature, as well as in reaction to their emotions or moods. The ability to change color allows chameleons to adapt to their surroundings and become more comfortable, as well as helping them to communicate.
Chameleons change color to reflect or absorb light and temperature. When lying in the hot sun, for example, chameleons may change to a lighter color to reflect the sun’s glare. As for temperature, when it’s cold, chameleons can darken to absorb as much heat as possible. However, in general, most of the time, color changes are due to mood swings. So when chameleons change color, they may be doing so because they are expressing their emotions, such as anger or fear.
