The chameleon is an animal known for its remarkable ability to change color, a skill primarily used for communication and camouflage. This color change is controlled by intricate hormonal and neural mechanisms affecting special pigment cells in their skin, known as chromatophores. Chameleons change their hue based on various factors, including mood, temperature, and light, as well as to blend into their surroundings for protection from predators. Interestingly, these reptiles are not just limited to green; they can showcase a vibrant array of colors, including blue, yellow, and red, depending on their environment and emotional state.
