Emblemetric, a new website by James I. Bowie.
“Working with its database of more than 1.2 million logos dating back to 1884, Emblemetric examines patterns in design over time and across industries, including those related to the births of new styles, deaths of old trends, color use, and geography.”
“Color use in logos can also be addressed in terms of particular industries. The graph above shows the relative use across time of eight colors in the logos of seven selected industries (again, these shares sum to 100 percent).”
