Colors: Yellow, light blue, and dark blue
Meanings/Symbolism: Yellow is the sun. The light blue at the top is the sky. And the dark blue at the bottom is Lake Michigan. So, the sun rising in the morning out of Lake Michigan into the sky above.
Idealistically (although this is a very literal design), yellow represents hope and happiness. Light blue at the top represents peace and calm and relaxation. And dark blue represents the deep steady loyalty that is part and parcel of our Midwestern values.
