Male and female coloration scores. Relation of male and female scores for carotenoid coloration (A), melanin coloration (B) and total coloration (C). Dashed diagonals represent perfect sexual monochromatism (1:1 lines). Species at the lower left area of the plot are sexually monochromatic and little ornamented, at the upper right area are monochromatic and very ornamented, and towards the lower right area are dichromatic with males more ornamented than females.
