Detailed historical information about the school colors of Marian College is not available at this time. The college originally used a medium shade of blue, but in recent years this has darkened to a navy blue shade.
The Intercollegiate Bureau of Academic Costume (IBAC) assigned a hood lining pattern to Marian College in the late 1940s or 1950s. A list compiled by Kevin Sheard in Academic Heraldry in America (1962) described the college’s hood lining as royal blue with a gold chevron. A 1972 list from the IBAC described the college’s hood lining as “blue” (a medium shade of “true blue”), but the Bureau had by this point inverted Marian’s gold chevron to avoid duplicating the hood lining it had assigned between 1894 and 1912 to Vincennes University (blue with a gold chevron), another school in Indiana.
