Affective Effects of Fractal Dimension and Color Attributes on Preference for Chromatic Exact Fractals

This study investigates the impacts of fractal dimension and color attributes on preference for chromatic exact fractals through two experiments. Experiment 1 established the semantic differential scales suitable for affective evaluations of colored exact fractals. Experiment 2 collected affective evaluations for colored exact fractals from which four factors were extracted, including the Preference factor. Data analysis replicated the ascending trend between preference and fractal dimension level reported by previous studies. Regarding the color attributes, we detected an evident dislike for exact fractals in dark colors and a weak dislike for those in saturated colors. Further, exact fractals of warm hues were more preferred than those of cool hues on most tones.
