Abstract
A computer-implemented method for digital processing is provided. A set of tristimulus values representing a first color in a color space are received. A first representation of a first spectral curve corresponding to the first color is determined, where the first spectral curve is within a gamut of solid reflectances. A second representation of a second spectral curve corresponding to the first color is determined where the second spectral curve contains at least one reflectance wavelength outside the gamut of solid reflectances. Based on selection criteria, the first representation or the second representation is selected. The selected representation is then applied during digital processing.
