were analogous. The question was whether the achromatic aspect of
rod vision could be accounted for by the suggestion that opponent
chromatic colour processes activated by rod signals antagonized each
other completely when the eye was stimulated at scotopic intensities
in a chromatically neutral state of adaptation. If this suggestion was
correct, one would expect that by selectively chromatic adaptation
of the eye, it would be possible to obtain every principle hue of the
spectrum when test stimulating at scotopic intensities.
