Yep. Chameleons change colors, not to blend into their background, but depending on a number of emotional states. They change color when frightened, mating, fighting, etc.

"But I've seen photos/videos of a chameleon blending into the background!" - Yeah, but that's because they change so often, that eventually they'll match their backgrounds!

A chameleon would have little use for blending in, because their main prey, insects, tend to have an eyesight unfit to spot them when they are still; and being an apex predator, chameleons don't tend to have any natural predators.

Wonder about that!
