Green & Navy

Green and navy creates the Ralph Lauren Polo preppy Ivy League combination — because Ralph Lauren (Ralph Lauren Corporation, 650 Madison Avenue, New York City, the most commercially successful single American fashion designer in the history of American fashion, with annual revenues exceeding $6 billion and a brand value among the most recognized in global luxury fashion) specifically used the combination of ivy-league green and deep navy as the most characteristically American preppy warm-neutral-cool in the Ralph Lauren Polo brand identity from the company's founding in 1967 by Ralph Lauren (born Ralph Lifshitz, 1939, the Bronx, New York) — the green of the Ivy League campus lawns and the navy of the most traditional American nautical and collegiate wear creating the most specifically East-Coast-American-preppy and the most precisely Ivy-League-collegiate warm-neutral-cool in American fashion history.

The Ivy League athletic tradition (the Ivy League athletic conference, comprising Harvard, Yale, Princeton, Columbia, Brown, Cornell, Dartmouth, and University of Pennsylvania — the eight most historically prestigious private universities in the Northeastern United States, whose athletic teams and collegiate apparel in green and navy have defined the most specifically East-Coast-American-preppy athletic tradition since the late 19th century — particularly the Dartmouth Big Green's specifically Dartmouth-green-and-navy as the most institutionally distinctive Ivy League green-and-navy athletic tradition) creates the green-and-navy warm-neutral-cool at the most specifically Ivy-League-athletically-authentic and the most broadly East-Coast-collegiate warm-neutral-cool scale.

The preppy revival tradition (the publication of 'The Official Preppy Handbook' by Lisa Birnbach, 1980, the most commercially successful single-volume definition of the preppy aesthetic in American publishing, selling over 1.3 million copies and defining the green-and-navy Polo Ralph Lauren combination as the most specifically defining preppy warm-neutral-cool of the American East Coast upper-middle-class aesthetic tradition — the most commercially successful single definition of American Ivy-League-preppy style in publishing history) creates the green-and-navy warm-neutral-cool at the most specifically preppy-publishing-defined and the most broadly American-preppy warm-neutral-cool scale.
