Integrated combination of multiple colors as it is, color gestalt invariably troubles researchers as they seek to understand and analyze the complex constructions of affective factors. The author proposes a set of quantification methods for measuring color-affective factors of harmony, preference and structural composition. He also describes quantified models and interactive toolkits he built for both experimental purposes and user study. The author proposes a holistic method for understanding color combination that stands in contrast to conventional methods. Through this method, perception of color gestalt becomes computable and analyzable, inviting further research on interactive color computing and parametric design.
