Universal Color Index

Technology Application

The system could be used for the legal description of a trademark color as used in Corporation logos. More importantly it could be used to aid in finding a precise match for a color in color reproduction work. It would also simplify calculation of mixtures of colors in printing and painting.

Detailed Technology Description

University researchers have developed a novel system for the precise specification of color appearance (Munsell color space in our example but generalizable to most color appearance systems) from the reflectance spectra of the sample. The proposed process is the first time a method has been developed to calculate the transition from the location as defined by reflectance spectra to the perceptual location in a color appearance system (and the reverse) with analytic formula that maintain mathematical accuracy. The process simplifies the process many times over and gains in precision. We have criteria of precision that allows us to compare our process with the International CIE standard and show a great increase in precision.
