The green stripe represents the forest preserves and farmland in cook county, the yellow stripe represents the large amount of lakefront and beaches on Lake Michigan, the blue stripe represents the lake itself, and the yellow semi circle represents the sunrise on Lake Michigan. This sunrise represents how hardworking people are, as they often get up very early, as well as a new beginning that comes with the change of the county’s flag. Within the sunrise is the city of Chicago, since it is such a large portion of cook county and is the city that cook county is known for.
