- Subjects were tested using an adaptation from Goulart et al. [24] colour vision test, for the Alouatta genus. Length = Major axis of the ellipses in u’v’units of CIE 1976 chromaticity diagram units, Ratio = major axis length over minor axis length, Angle = relative angle of the major axis in degrees
