Kennedy chose a red-and-gold design from one of Loewy's initial concept sketches, asking him to render the design all in blue. Loewy's also drew inspiration from the first printed copy of the United States Declaration of Independence, suggesting the widely spaced and upper case "United States of America" legend in Caslon typeface. He chose to expose the polished aluminum fuselage on the bottom side and used two blues – Steel blue associated with the early republic and the presidency, and a more contemporary water blue to represent an America both rooted in the past and flying inexorably into the future.
