To resolve the problem of product sustainability for reusable bags, the interpretive structural modeling (ISM) approach was used in this study to determine and analyze the correlation between different color combinations of reusable bags. Afterwards, the product hierarchy is then built by the decision making trial and evaluation laboratory (DEMATEL) approach so that the importance of color to design and the resulting effects can then be determined. The cluster analysis by the analytical network process (ANP) is also implemented in order to analyze the market. The framework with the optimal weight among several modularized color schemes is determined accordingly. A case study on the design of reusable bags was inspired by a Mondrian artwork. Based on the linguistic information, it demonstrates the creation of new color schemes from the proposed systematic grouping method. A color coding rule is proposed and applied to the modularized development of colored products. The results that are obtained from this case study allows a designer to determine the factors of common color schemes and color matching. As a result, the most effective colors can be highlighted for improving the color schemes of sustainable products.
