Apparatus for obtaining color raw material for cosmetics

An apparatus for obtaining a raw material comprising:

• an input unit for receiving a target color for development;
• a formulation sample group generation unit for generating a formulation sample group according to the target color for development;
• a formulation sample improvement unit for outputting the formulation sample group as an improved sample group using a genetic algorithm;
• and
• an improved sample group convergence checking unit for outputting the improved sample group to the formulation sample improvement unit or an output unit according to whether all samples in the improved sample group converge to a preset reference range,
• wherein the output unit outputs raw material information for manufacturing color cosmetics having the target color for development based on the improved sample group output from the formulation sample improvement unit,
• the raw material information includes a content of at least one raw material, and
• the formulation sample improvement unit includes
• a sample candidate derivation unit for generating a combination sample by selecting any one of existing samples and any one of the remaining existing samples as a random sample, mutating the random sample into a mutation sample by performing interpolation to select a value between a content contained in the selected existing sample and a content contained in the random sample, and then combining the mutation sample with the one of the existing samples,
• a sample evaluation unit for calculating the first color difference between a predicted color development value of the selected existing sample and the target color for development and the second color difference between a predicted color development value of the combination sample and the target color for development, and
• a sample selection unit for outputting the sample having the smaller value among the first and the second color differences as an improved sample in the improved sample group.
