Color information is one of influential factors which affects human behaviors. Relationships between coloration of interface and operational performance are well known; and many previous researches have shown evidences of relationships between coloration and users’ emotion. Consequently; it is expected that there are important effects between interface color design; emotion and operation. Nevertheless; almost of the previous researches were done in which impact of color on emotion or task performances were investigated independently. In this paper; a novel model which represents relationships between color design; emotion and operation is proposed. Structural Equation Modeling (SEM) has been employed as the method for generating representative models. Users’ performance and their impression for the interfaces are used for the data to generate SEM models. To obtain users’ performance data; experiments have been conducted with simple computer software of arithmetical calculation in which touch panel interface is used. Furthermore; questionnaire approach has been used to obtain users’ impressions for interfaces. By using the proposed scheme; we can verify the effects of touch panel coloration on operator’s feeling; and clarify how the feelings affect the operations. To verify the efficiency of the proposed scheme; two representation models; one is based on the proposed scheme and the other is based on the traditional scheme; have been generated and analyzed. As a result; the former model can illustrate the relationships between color design and the operational performances better than the latter one.
