Chameleons Change Color to Blend In

Chameleon Color Change Many think chameleons shift colors just to hide in their environment, but that’s only part of the story. Camouflage isn’t their main goal. They change hues mostly to control body temperature and talk to other chameleons. They pull off this trick with special skin cells called iridophores, packed with nanocrystals. Adjusting these crystals shifts the light they reflect, changing their color.

For instance, they darken to soak up heat when cold or lighten to stay cool in the sun. Color also shows mood, aggression, or mating interest—like a male flashing bright shades to impress or intimidate. This complex skill goes way beyond just blending in.
