Brand logos are essential for companies and their design is at the heart of graphic design. In a global market, the number of competing logos has grown exponentially. We present a software tool that helps designers to semi-automatically analyze large sets of graphics. The results of the color analysis help designers to make informed choices for their designs. We present two case studies that demonstrate the operation of our software tools. The first case study analyzed the logos of countries: flags. The second case study analyzed the logos of financial institutions. In addition to the descriptive statistics, we also put the results of the color analysis into relation with social-economic indicators. Our software tools have been successful at offering logo designers valuable information for the design of new logos. (c) 2013 Wiley Periodicals, Inc. Col Res Appl, 40, 72-84, 2015
