As a method of supporting idea generation in automobile product development, the authors have constructed the Automobile Color Matching Model (ACMM), which is a model for matching automobile exterior and interior colors while taking into account consumer preferences. The actual approach for the research was to first determine the parts relevant to automobile color matching by using an eye camera and an electroencephalograph to observe the responses of women in their twenties, who were the

... ts of the research. Next, a customer preference survey was conducted and the research subjects' preferences were analyzed by using cluster analysis to categorize the research subjects according to their preferences and using principal component analysis to identify sensory words that describe requirements for automobiles. Then, color surveys were conducted for each preference group, and the obtained data was analyzed using quantification method type III to identify key colors. Analytic hierarchy process (AHP) was then used to conduct automobile color matching. The effectiveness of the resulting Automobile Color Matching Model (ACMM) has been verified and the required results have been attained.
