Iowa law officially describes the state flag.
The design consists of three vertical stripes of blue, white, and red, the blue stripe being nearest the staff and the white stripe being in the center. On the central white stripe is depicted a spreading eagle bearing in its beak blue streamers on which is inscribed the state motto, "Our liberties we prize and our rights we will maintain" in white letters, with the word "Iowa"; in red letters below the streamers.
Iowa state seal.
Cornell Gebhardt assigned meaning to each color of the flag: blue represents loyalty, justice, and truth; white stands for purity; red symbolizes courage. The Des Moines Register suggested that the design hearkens back to Iowa's history as a French territory, with both flags containing blue, white and red from left to right, though Iowa's banner has a wider white section. The Register also stated that the word "Iowa" written in red symbolizes the Iowa soldier (writing) in letters of blood on the white page of history his unalterable determination to defend the ideals represented by the banner and its wonderful motto.
