When discussing the visual identity of the United States, the specific nomenclature for the blue color used on the American flag often goes unnoticed. Most people recognize the shade immediately, yet struggle to articulate its exact name beyond the basic description of "blue." This common shade, however, has a distinct identity governed by official standards, historical precedent, and design specifications that ensure its consistency across every banner manufactured.
The Official Standard: Old Glory Blue
Contrary to the random digital hues found on a typical color picker, the blue field of the American flag is precisely defined by federal law. According to Title 4 of the United States Code, which outlines the codified laws regarding the flag, the specific shade is referred to as "Old Glory Blue." This designation moves the color from a generic description to a proper name, signifying a standardized visual language intended to unify the appearance of the flag regardless of where it is produced, from mass-market retailers to government installations.
Pantone Matching System (PMS) 282
For designers, manufacturers, and printers tasked with reproducing the flag accurately, the language of digital RGB values is insufficient for ensuring physical fidelity. To translate the digital concept into a tangible, mixable ink, the industry relies on the Pantone Matching System. The official PMS designation for Old Glory Blue is PMS 282. This standardized formula allows printers worldwide to mix the exact same deep, rich blue, ensuring that a flag printed in New York matches the one printed in California without deviation.

Web and Digital Color Representation
In the context of web design and user interface development, colors are often defined using hexadecimal (HEX) or RGB values. While the official Pantone standard remains the physical benchmark, the digital approximation of Old Glory Blue is represented by the hex code #3C3B6E. This specific combination of Red, Green, and Blue light values produces the dark, subdued blue observed on the fabric, translating the physical standard into a format that web browsers can interpret correctly for digital displays of the flag.
It is important to note that variations can occur depending on the specific digital color profile. While #3C3B6E is the most widely accepted hex code for Old Glory Blue, some official government websites or vector file libraries might utilize a slightly lighter variant, often associated with the hex code #3C3B6E. This variance usually stems from the difference between working in a saturated digital environment versus the muted, organic dye penetration of cotton bunting, but the core visual intent remains the same: to represent the specific shade defined by tradition and law.
Visual Depth and Historical Resonance
The choice of this specific blue is not arbitrary; it carries historical and aesthetic weight. The deep, dark tone of Old Glory Blue provides a stark and dignified contrast against the white stripes and the red stars. This contrast ensures that the canton—the blue rectangle in the upper left corner—recedes slightly, creating a sense of depth that makes the white stars appear to float upon the surface. Psychologically, this shade of blue evokes feelings of vigilance, perseverance, and justice, aligning perfectly with the ideals the flag represents.

Furthermore, the name "Old Glory" itself is a character in the flag's history. Originally coined by sea captain William Driver in the 1820s, the term personifies the flag as a living entity. Consequently, "Old Glory Blue" serves as a linguistic link between the physical object and the patriotic sentiment it inspires. By assigning a specific name to the color, rather than merely calling it "blue," we acknowledge the intricate relationship between the material flag and the abstract ideals it embodies, ensuring that the color remains a constant symbol regardless of the flag's age or condition.
