College of Idaho
Idaho
1891
According to Our College Colors (1949) by Henry L. Snyder, students at the College of Idaho selected purple and old gold as their school colors in 1891 when the college was established.
Citations in the World Almanac (listed by cover date; color information is from the previous year): purple/old gold (1923-1935)
The College of Idaho was not cited in Intercollegiate Bureau of Academic Costume (IBAC) lists from 1927 or 1948, so the Bureau might not have assigned a hood lining pattern to the college until the late 1940s or 1950s. In Academic Heraldry in America (1962) and Academic Dress and Insignia of the World (1970), Kevin Sheard wrote that the College of Idaho was using a hood lined purple with a gold chevron, but a 1972 list from the IBAC more accurately described the hood lining as purple with an old gold chevron.
The Bureau used an identical description for the hood lining of Knox College, but in actual fact Knox’s colors were royal purple (dark purple) and old gold.
