Uncertainty relations for opponency of perceived chromatic states

In a previous work, the theoretical existence of uncertainty relations governing chromatic opponency for general chromatic states within a quantum information-based model of color perception has been established. In the present study, we extend this result by deriving uncertainty relations for chromatic states perceived by a human observer, modeled as a quantum effect. Our analysis indicates that, once the presence of an observer is explicitly taken into account, only uncertainty relations associated with highly saturated stimuli are likely to be experimentally detectable.
