The flag of Wyoming consists of the silhouette of an American bison. The red symbolizes the Native Americans and the blood of pioneers who gave their lives. The white is a symbol of purity and uprightness. The blue is the color of the skies and distant mountains. It is also a symbol of fidelity, justice and virility. The bison represents the local fauna, while the seal on it suggests the custom of branding livestock. (Source: Wikipedia.org, CC BY-SA)
