Background concept -
Chameleon's change colors due to emotions, basically a visual signal of mood. On a molecular level, the skin of a chameleon is actually several layers of specialized cells called chromatophores which are able to change their pigmentation through the use of xanthophores, erythrophores and iridiphores - which bring about the different hues of yellow, red and blue. They also contain guanine which alters DNA and melanophores which are brown pigment with melanin in them.
Wired to the nervous system, these specialized cells are locked away in sacs and only released when discharged, allowing the color to spread out across the cells, effectively giving the a coat of paint, if you will.
Basic hues that could be worked into the nano-cells would be pink, blue, red, orange, green, black, brown, light blue, yellow, turquoise and purple.
Dispersion is rapid, almost instantaneous and are controlled by the thoughts of the brain.
chemical breakdown -
Chromatophores are pigment-containing and light-reflecting ogranelles in cells.
Can be triggered by neurotransmitters (meaning they can be controlled by thought if correctly applied)
A limited physiological color change known as background adaptation which uses darkening and lightening of the skin pigmentation to mimic the immediate environment.
Chromatophores are usually generated in the neural crest of the neural tube. These cells have the ability to migrate long distances, in essence allowing the chromatophores to populate the skin quickly and completely.
If applied to the skin, they enter through the ectodermal tissue of the dermis.
Nanogen affect -
The nanos would be released as triggered and would adhere to the dermal melanocytes and change the human chromatophore-like cells into chromatophores capable of pigment translocation, resulting in an apparent change in color to effectually 'blend' with the environment around them. Flat, the dermal melanophoric nanogens would adhere to the thin dermis as well as stacking to create a DCU effect (dermal chromatophore units) that create an almost basket-like weave. These units would work simultaneously to both alter the pigmentation as well as reflect light.
unlike nanosurgeons which react to blood loss as the 'trigger' for action, if these are dispersed as nanogens, they would require some sort of conscious trigger and storage system. Therefore, a containment system chrome cyberware and then the nanogens into the containment system. And, the nanogens would be used up with each use, therefore over time needing new nanogens installed?
containment system of some sort attached to the base of the hypothalamus within the brain, linking it to the nervous system to allow for quick conscious release of nanogens.
side effects -
*-*cold-blooded species tend to have these - some effect from that - loss of heat regulation and loss of control of evaporation of fluid
*-*albinism for a period of time (loss of pigment)
*-*skin is thinner, more susceptible to injury
