Abstract
A method and system create a color match that reproduces a color standard. First, the color spectrum of a color standard is read. After reading the color spectrum, a plurality of formula keys corresponding to the color spectrum of the color standard are obtained. Each of the plurality of formula keys have a different combination of colorants that formulate the color standard. The plurality of formula keys are restricted to combinations that have a greater probability of generating a color match with the color standard. Each of the plurality of formula keys are then evaluated in order of probability of generating a color match with the color standard to determine whether the colorants in each formula key can be combined to reproduce the color standard. The formula keys having a greater probability of generating a color match are evaluated prior to formula keys having a lesser probability of generating a color match. Each evaluation generates a degree of match between each formula key and the color standard. The degrees of match generated from all of the plurality of formula keys are then compared to determine the best match with the color standard. The formula key having the best ma…
