The Intercollegiate Bureau of Academic Costume (IBAC) must have assigned St. Vincent College a hood lining that was olive green with a gold chevron before 1906 or 1907, because by that date Baylor University had been assigned a hood lining that was olive green above gold, divided per chevron. Typically the IBAC would assign a heraldic chevron to the first college or university to be registered with a certain pair of colors, then schools that were registered with those same colors thereafter would be assigned a hood lining with a different heraldic division, such as two chevrons, a division per chevron, a “zone” (bar), etc. So St. Vincent’s registration with the Bureau would have predated Baylor’s registration.

The first Intercollegiate Bureau description of St. Vincent’s hood lining was in a 1927 list. It stated that the hood lining was olive green with a gold chevron, a hood lining description that did not change in subsequent IBAC lists. The IBAC typically defined “olive green” as a dark shade of olive green; by comparison, researcher Kevin Sheard described St. Vincent’s hood as “forest green with a yellow gold chevron” in Academic Heraldry in America (1962).
