ABSTRACT:
A system comprising a plurality of comparison samples each having a reflectance spectrum and being configured to substantially simulate a color of a keratinous element having a reflectance system. The reflectance spectrum of each comparison sample may be substantially similar to the reflectance spectrum of a respective keratinous element such that the comparison sample and the keratinous element appear to an observer to have substantially the same color under at least two differing illuminants.
