How do chameleons change colour?

I need to know, because I want to be able to do it.

Please explain.

    They are very clever.

    That means you'll never be able to do it. :(

    *runs for ze hills* :p

    Im sure i remember reading somewhere, but it might just be something i dreamt up, so here goes...

    In their skin they have this polymer which in its normal state is tiny, but when an electrical current or heat or something is applied to it, it can expand to something like 100 times its own size, and the expanded polymer is a different colour to the condensed one, and so the chameleon changes colour.
    They have different types of polymers for different colours, and different currents make different ones expand.
    People are trying to harness it for use in something or other. Im trying to find the srticle but with no luck. I'll keep looking!

    Still want to give it a go?

    :)

    NO NO NO!!!
    basically its due to them bein cold blooded and wen they go on different coloured things (which absorb different amounts of heat) their colour changes accordingly cos their blood heats up due to the chemical changes occuring in the blood!

    they are actually communicating using colour

    And they can change colour very rapidly without changing environment. So how does the blood thing work?

    Ok. So my memory had faded slightly- we are the ones using polymers and they use bags of dye...
    achieve their rapid changes by squeezing small bags of pigment. Their skin contains sacs filled with various colours, to which muscle fibres are attached. When the muscles contract, the sacs become large, and the area they cover appears coloured. Relaxing and lengthening the muscle fibres squeezes the sacs into a small volume, making the colour appear to vanish.
    WHich should be here

    The change in colour is associated with an electrochemical reaction, the change in colour is reversed when the polymer is reduced. The possibility of works with thin films of different surfaces and the potential colour correlation allows the design of canvases which linked to a video camera and a program of enviroment mimetization will be able to behave as chameleons or cuttlefish, dissappearing in the background.
    which is from here

    Knew i'd read it somewhere!

    Thanks :D

    I don't have bags of dye inside me though. :(

    So I'll have to go for polymers. heh.
