Chameleons don’t only change color to blend in — it’s also for mood and temperature!
They have iridophores — tiny crystals under the skin that reflect light.
By adjusting crystal spacing, chameleons shift skin color like a natural prism.
Chameleons show emotion — stress, excitement, or aggression — by changing color.
Darker colors absorb heat, lighter shades help cool down — like a living thermostat.
