Claim 22:
23. A hair dye color conversion system for performing color scanning analysis, the system comprising:
one or more processors;
an input device that enables a user to input hair dye color information into the system; and
a memory device storing a set of instructions that when executed by the one or more processors, causes the one or more processors to:
scan hair to obtain color values representing a hair color;
generate mathematical values from the obtained color values for individual hair dye colors and color component percentages in a hair dye color combination using an original color space in the first manufacturer color line;
apply a transformation to mathematical values of individual hair dye colors in the hair dye color combination for the first manufacturer color line, wherein the transformation is a modified Kubelka-Munk (KM) transformation;
multiply the modified KM transformed values of the individual hair dye colors in the hair dye color combination for the first manufacturer color line by the color component percentages of the individual hair dye colors in the hair dye color combination and then summing them;
retransform the summed modified KM transformed values of the individual hair dye colors in the hair dye color combination back into mathematical values in the selected original color space; and
determine multiple hair dye colors of a second manufacturer color line that are combined to create the retransformed mathematical values for the individual hair dye colors in the hair dye color combination.
