Purkinje effect: History, Applications & Art

The Purkinje effect or Purkinje phenomenon, sometimes called the Purkinje shift (often pronounced /pərˈkɪndʒi/), is the tendency for the peak luminance sensitivity of the eye to shift toward the blue end of the color spectrum at low illumination levels as part of dark adaptation. In consequence, reds will appear darker relative to other colors as light…
