Fig. 2. Assessing dichromatism in the human visual range. Geometric mean regression
of segment classification estimates of sexual dichromatism in the human visual
(400–700nm) range against human visual estimates
(r2=0.73, N=978, P<0.0001). Segment
classification scores were calculated using spectrophotometer data. Scores for
each index were standardized to a mean of zero and a standard deviation of
one.
