A method of measuring and comparing the greyness (unwanted spectral absorptions) of process colorants has been developed. The method uses the 1976 CIELAB color space and, in effect, makes a chromatic match of a trial colorant with a reference Cromalin® ‡ color and then calculates greyness from the difference of their values of CIE 1976 lightness L*.
