I remember reading an old account that in the days of B&W TV, Fechner colors could also be displayed on screen and had been used in some commercials. That might weird some people out... how is this black and white TV showing me color?
The effect does not seem to be standardized between people, or else maybe a Fechner color based color viewing system could be designed. Perhaps it could still be, but it would have to be tuned to the person.
Fechner color can’t really be tuned, as it is not a fixed bandwidth, but a dynamic illusion that changes constantly.
As much as anything, the illusion it creates is based on the electro-chemical behavior of the brain, which constantly changes. Through imaging it looks like lightning within a storm cloud, darting about almost randomly.
