Heterochromatic brightness matches were carried out between bichromatic mixtures of lambda 1 and lambda 2, and a 100 td white reference light of 2 degrees arc. Two characteristic properties of additivity failure were observed. One is the asymmetrical property of additivity failure, that is a remarkable brightness reduction at the luminance ratio where the hue cancellation occurred. The other is the superadditivity for a mixture of a violet and a white or a middle-wave light. These properties were accounted for by a nonlinear vector model on the assumption that the opponent-color channels outputs were nonlinearly transferred to the brightness perception.
