The claim

Chameleons change color to blend in and match whatever background they are on.

What the evidence shows

Chameleons do change color, but not primarily to match their background. Their color shifts are driven mainly by communication — signaling mood, dominance, or readiness to mate — and by temperature regulation, controlled by hormones and the nervous system. They cannot transform to copy any background or pattern; for camouflage they tend to rely on a generic greenish-brown resting color rather than precise background-matching.
