Abstract
More than one hundred years ago, von Kries model has been developed for a description of the chromatic adaptation phenomena of the human visual system, and various chromatic adaptation models based on von Kries model have been developing in today. However, there remain some important issues related to von Kries model which have not been clarified up until now. Succeeding to the first report, the theorems derived for subtractive color mixture problems by us will be applied to the important issues related to von Kries model.
