The public mark of the City of Chicago

Welcome to the Chicago Design System

The Chicago Design System is the public identity for the City of Chicago & its people–Chicagoans.

It is an inclusive, cost-effective update of our public identity for the 21st century, built on the history of Chicago and our civic heraldry.

Here you can find basics (colors, type, icons, the star), our new public mark, our updated seal, and high quality versions of our municipal symbols (flag, device, pennant, badge).
