A psychological test was performed by using computer-generated color patterns, which were composed of ordered repeats of random color arrangements, and the effects of the repeat number were investigated. The results were analyzed in terms of power spectra of the Fourier transform of the color patterns, and it was clearly found that the psychological evaluation depended strongly not only on the amount but also on the degree of concentration (or scatter) of the power spectrum. Furthermore, in order to predict the psychological values of the color patterns, multiple regression analyses were done by using three models with 13, 14, and 15 specified variables that were obtained from the Fourier transform. It was found that the multiple correlation coefficient increased considerably by introducing the second-order term of a variable that indicates the degree of concentration of the dynamic components, especially for the evaluation of beautiful-ugly or interesting-boring.
