Abstract
The present invention discloses a method and system for selecting a previously used color match from a plurality of previously used color matches that best matches a color standard. In the present invention, each of the plurality of previously used matches are identified with a spectral reflectance and a color formula. The present invention includes measuring a color spectrum and spectral reflectance of the color standard. The spectral reflectance of each of the plurality of the previously used color matches are then processed. The processed plurality of previously used color matches are searched for a set of previous color matches that have a high probability of being adapted to attain the color spectrum and spectral reflectance of the color standard. Next, a color match that provides the best match with the color of the standard is determined from the set of previous color matches. The formula of the best match is used to reproduce the color of the standard. The color formula of the best match is adapted until there is an acceptable match with the color of the standard.
