Most people are familiar with the Golden Gate Bridge and many have even seen it in person while visiting San Francisco. However, until I saw this video I never gave much thought to the unusual color of the bridge. The orange hue of the Golden Gate Bridge was an accident of history. San Francisco owes the iconic color of its bridge to Irving Morrow, the consulting architect, who noticed the striking reddish-orange hue of the primer coat, and lobbied to have it made permanent.
