There are real substances that become transparent or opaque or reflective when 
exposed to some electrical field, and some that do the same if a beam of light 
hit them in a sertain way. The later are colour specific: a white beam pass 
trough, a red control beam will cause it to reflect red of the exact same wave 
length as that of the control beam. There are ongoing researches done to create 
a working computer from those. They do have some working prototypes that have 4 
states "bits" for 30 or so independent colours...
