The purpose of this study was to create a harmonious color model with fragrance, depending on the similarity of impressions from the color and the fragrance. This study consisted of two experiments. Experiment 1, our objective was to extract dimensions in fragrance impressions and consider harmonious/disharmonious colors with each fragrance. One hundred subjects were asked to evaluate their impression of eight fragrances (by the Semantic Differencial method) and to select harmonious colors and disharmonious colors with each fragrance from color chart consisted of 18 colors. By factor analysis, MILD factor and CLEAR factor were extracted for the dimensions of fragrance impressions. Also, by multiple regression analysis, we could construct predictive formulas of harmonious/disharmonious color for fragrance. Experiment 2, we confirmed the predictive formulas in Experiment 1 reversibly. We asked 80 subjects to evaluate their impressions, degree of MILD and CLEAR, of 15 fragrances by the Visual Analog Scale. Subjects were also asked to select harmonious colors and disharmonious colors with each fragrance from 18-color chart. To calculate the predictive rates of selection of harmonious/disharmonious colors with each fragrance, we applied the MILD and CLEAR scores of 15 fragrances to the predictive formulas in Experiment 1. We also calculated the correlation coefficient between those predictive rates and the actual rates of selection of harmonious/disharmonious colors that we get in Experiment 2. As a result, we found that the predictive formulas were quite accurate in most cases, suggesting that it is possible to develop a harmonious color model for fragrance.
