chamelons do not modified their hues by accumulating or dispersing pigments with their skin cells

Hi,

Here is your answer,

It's a simple yet awesome mechanism.
Earlier it was thought that the skins of chameleon had different cells containing different pigments - yellow, red, melanin for black. And chameleons changed colour to darker shades by spreading their darker pigment melanin. This thought was discarded as it was found that chameleons don't contain green pigmented cells, so how come they have green coloured skin when they don't want to change their colour.
Physicist and biologist at the University of Geneva proved this theory wrong.
Chameleon contains yellow pigments. Beneath this, it contains tiny nanocrystals regularly arranged in a lattice. The green colour which everyone sees on a chameleon are in fact the combination of yellow pigment and the blue light.
When the crystals are relaxed(calm chameleon), the lights having low wavelengths(blue) gets reflected by the lattice and gets mixed with yellow pigment, thereby imparting green colour to the chameleon. The long wavelengths(orange,red) passed through the lattice without outer reflection, hence not combining with yellow pigment at all.
When a chameleon wants to change its colour into much darker shade, then it excites its lattice, creating bigger spaces between the crystals, which can now reflect long wavelengths(orange, red). These reflected dark shades combine with yellow pigment to produce large range of colours including brown et al
