This standard specifies that, under a standard light (hereinafter referred to as reference light), sample pairs (hereinafter referred to as conditional isochromic pairs) have different spectral characteristics but the tristimulus values match or are almost equal. ) is determined by the degree to which the tristimulus values do not match when the illumination light is changed.
