Instead, the perception of magenta arises when the visual system receives light containing both longer wavelengths (reds) and shorter wavelengths (blues/violets) without significant stimulation in the mid-range [green regi…

    Psycho-Physiological Impact and The Satori Anomaly
    While standard dark adaptation is a passive physiological adjustment, certain extreme mental states have been anecdotally linked to transient alterations in scotopic processing. Practitioners of Satori Katsuryoku report a momentary sharpening of low-light perception, specifically associated with the perceived recalibration of all blue hues to a wavelength correlated with the [atmospheric refraction index](/entries/atmospheric-refra…
