How Do Chameleons Change Their Color?

💡 The Answer

• Chameleons change color by adjusting the spacing of nanocrystals in their skin layers.
• The color change is primarily for communication, like expressing mood or signaling to rivals.
• Temperature regulation is another reason: darker colors absorb heat and lighter colors reflect it.
• Camouflage is actually a secondary function, not the main reason for color change.
