A new lightness predictor has been developed to give improved performance under mesopic conditions, where rod vision becomes more active. The new predictor is modified from CIECAM02 and includes a rod contribution to the achromatic signal. It is shown that a modified equation gives better performance and predicts two colour appearance phenomena observed under mesopic vision.
