Creation of automobile exterior color design approach model “A-ACAM”

The quality of a car´s exterior color has become a major aesthetic factor (preference) influencing the car buying process. Thus, for this study, the authors have created “A-ACAM” (Automobile Exterior Color Design Approach Model) and the model´s effectiveness has been verified. In creating the model, the authors utilized information from their own research, entitled “Kansei engineering in automobile”. They first determined the four elements most desired by young people when choosing exterior colors (classy, luxurious, dignified, and sporty). Next, they determined the six elements of color (hue, luminosity, intensity, shine, opacity, and graininess) that influence young buyers the most. Correspondence analysis was then applied with the aid of statistical science (multivariate analysis) in order to correlate the young people´s preferences with the color elements, enabling the authors to determine the degree of influence of each of the color elements. Based on these findings, the model has subsequently been applied in exterior color development (paints and painting methods), demonstrating significant results.
