Secrets Revealed Of How A Chameleon Can Change Colour
In some ways a Chameleon gets a bad press as people with bad practices are often compared to them. Sales people are often referred to as Chameleons as they change their actions (colour) to make a sale. It’s an unfair comparison as Chameleons are blending in with their background and not trying to sell you a dodgy second hand car! Enough of that, we now know that Chameleons rely on very small crystals under their skin that can change shape and therefore reflect different wavelengths of light delivering this incredible colour change.

When a male panther chameleon is calm, he is usually green. But if a macho male approaches he might become competitive or angry, and often changes to a bright yellow and red.
Some species, like the panther, can change colour in under two minutes.
Many lizards are known to have several layers of cells with different pigments in them, which can make their skin brighter or darker.
Now it has been shown that chameleons do not use this same process when they change from, say, green to yellow.
Instead, tiny crystals called iridophores, found just under the surface of their skin, are the key. These crystals contract and expand when a chameleon is excited or under duress.
