G0 Colorants
  DOI :  10.2352/CIC.2010.18.1.art00046  Published OnlineJanuary 2010

Mixtures of colorants that faithfully render G0 colors at maximum NCS chromaticness for the twenty-four (24) NCS aim hues were derived computationally. Candidate colorants were modeled with a Gaussian function smoothly varying as in natural materials distinguishing G0 as the limit of object color independent of MacAdam's loci of pure spectral color. Spectra were synthesized using a gradient-based, nonlinear optimization with an objective function that maximized the color inconstancy of the mixture between two illuminants, CIE D65 and Illuminant A, thereby synthesizing a theoretical target set most sensitive to those changing conditions of illuminant that affect colorimetry.
