Considering that most graduation robes are black, it's always stunning to see the graduation procession with its splashes of color on hoods and sleeves. Unless you're listening to a really terrific graduation speech, you're probably sitting there taking in the spectacle and wondering what all the colors mean. There's a symbology there, with each color representing a different academic discipline, and some - dark blue, for example - signifying that this person holds a Doctorate of Philosophy, or Ph.D. (Someone with a doctorate that is not a Ph.D wears the color that goes with his specific disipline.)
Universities have their own traditions when it comes to graduation garb - Harvard, for example, puts all its doctoral candidates in crimson gowns and its undergraduates pair crimson hoods with their black gowns - but most follow an inter-collegiate color code set out in 1893 and tweaked over the years to reflect the addition of new majors.
These are the colors that represent the most common majors:
- Architecture and city planning: violet-blue
- Business and accounting: a beige color commonly referred to as “drab”
