America's national color palette dates back to 1777, when the Second Continental Congress passed a Flag Resolution calling for 13 red-and-white stripes and 13 white stars on a blue field. The resolution established the basic elements of the flag but left many details unspecified, resulting in a variety of early designs. Four decades later, the Flag Act of 1818 standardized an important feature of the design by fixing the number of stripes at 13 to honor the original states and requiring a new star for every state admitted to the Union.
Then in 1953, shortly after President Dwight D. Eisenhower took office, his administration began to plan for the eventual admission of Alaska and Hawaii as the 49th and 50th states. One of the smaller details requiring attention was how adding two new white stars might alter the design of the existing United States flag. This challenge evidently captured the public’s imagination.
