    How Do Chameleons Change Color?


    CHAMELEONS ARE FAMOUS for their quick color-changing skills. It’s a common misunderstanding that they do this to camouflage themselves against a backdrop. But chameleons mostly change color to manage their temperatures or to gesture their intentions to other fellows.

    Several chameleon species are able to swap their skin colouration. Its skin has an exterior layer which contains pigments. Also, under the coating there are cells with guanine crystals.

    By changing the space between the guanine crystals, Chameleons change colour., which exchange the wavelength of light reflected off the crystals which further more swamp the colour of their skin. Dissimilar chameleon species are able to vary their colouration and pattern through amalgamation of pink, blue, red, orange, green, black, brown, light blue, yellow, turquoise, and purple.

    Usually, the pigments are caged away in the inmost of the tiny sacs within the cells. Its nervous system tells specific chromatophores to expand or contract when a chameleon encounter changes in body temperature or mood. This changes the color of the cell. By varying the venture of the unlike chromatophores in all the layers of the skin. The chameleon can manufacture a whole variety of colors and patterns.


    But colour change in chameleons has functions in camouflage, but most commonly in general signalling and in reactions to warmth and other conditions. The relative importance of these functions differs with the circumstances and with the species. Colour swap indicates a chameleon’s physiological condition and intentions to other chameleons.

    Another reason why they change color is to regulate their body temperatures is because chameleons are ectothermic. They either changes to a darker color to absorb light and heat to raise their warmth, or to a lighter color to reflect light and heat, thereby either stabilizing or lowering their body temperature. Chameleons tend to display brighter colours when showing aggression to others , and darker colours when they backdown or give up.
