About the Harmony II Flag
The 6-pointed star represents the 6 regions of Cook County. The star’s Chicago-flag-styling serves as a nod to the City of Chicago as the seat and centerpiece of the county.
A large, yellow star represents the bright sun that shines over everything. The green stripes represent our nature and forest preserves. The yellow stripes invoke the interconnected highway system and the heights of our skyscrapers.
The blue spaces in-between are our waterways and lakes. When these colors come together, they also represent the diversity of the county, as sort of a fabric interwoven, uniting the different people of the county together.
