System and method for hair dye color conversion

A system for performing hair color scanning analysis, wherein the system uses converted mathematical RGB data of multiple hair dye colors for a first manufacturer color line into a product matrix that accounts for different hair dye color percentages in a hair dye color combination, the system comprising:

• a memory device storing a set of instructions that when executed by one or more processors, causes the one or more processors to:
• apply a transformation to mathematical values of individual hair dye colors in the hair dye color combination for the 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 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 a selected original color space;
• and
• determine multiple hair dye colors of an another manufacturer color line that are combined to create the retransformed mathematical values for the individual hair dye colors in the hair dye color combination in the original color space.

A hair dye color conversion system for performing color scanning analysis, wherein the system uses mathematical values generated from obtained color values for individual hair dye colors and color component percentages in the hair dye color combination, 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:
