Detailed historical information about the gold and royal blue school colors of Rockefeller University is not available at this time.
The chevron was by far the most common heraldic division the Intercollegiate Bureau of Academic Costume (IBAC) employed to divide the two or three colors in an institution’s hood, but beginning in 1895 the “double chevron” was also used quite frequently. The typical width of a normal chevron was between three and four inches, but the double chevron pattern used two chevrons of about 1½ inches in width placed approximately two inches apart so that the color of the hood lining showed between them.
Rockefeller University did not appear in early IBAC lists from 1927 or 1948, so the IBAC might not have assigned the college a hood lining until the late 1940s or 1950s. A list compiled by Kevin Sheard in Academic Heraldry in America (1962) described the university’s hood lining as golden yellow with two royal blue chevrons. Similarly, an IBAC list from 1972 said that the hood lining was gold with two royal blue chevrons.
