The design of the flag is based on an intersection, which is a shape that conveys both unity and movement. The deep blue represents the waterways that support commerce in the region, the light blue represents unity, both regional and international, as light blue can be found in both the flag of the United Nations flag and the city of Chicago’s flag. The white represents a fresh start and new beginnings. The entire grid is tilted forward to represent a future-facing outlook. This flag follows the principles of being simple, recognizable, and easy to remember.
