Evidence has accumulated that rod activation under mesopic and scotopic light levels alters
visual perception and performance. Here we review the most recent developments in the
measurement of rod and cone contributions to mesopic color perception and temporal
processing, with a focus on data measured using a four-primary photostimulator method
that independently controls rod and cone excitations. We discuss the findings in the
context of rod inputs to the three primary retinogeniculate pathways to understand rod
contributions to mesopic vision. Additionally, we present evidence that hue perception is
possible under scotopic, pure rod-mediated conditions that involves cortical mechanisms
