Abstract:

The authors developed the MatLab program for modelling the observation of an object and a background of different chromaticity at the constant luminance and obtained the uniform-chromaticity curves with shape close to elliptical. The results of colour thresholds calculations are compared with MacAdam ellipses and an explanation is given for their differences. Based on the statistical model of threshold colour vision, the authors derived expressions for the physiological uniform colour space.
