  • «Human eye – anatomy». Britannica online. «The Purkinje shift has an interesting psychophysical correlate; it may be observed, as evening draws on, that the luminosities of different colours of flowers in a garden change; the reds become much darker or black, while the blues become much brighter. What is happening is that, in this range of luminosities, called mesopic, both rods and cones are responding, and, as the rod responses become more pronounced – i.e., as darkness increases – the rod luminosity scale prevails over that of the cones.»
