Information about the history of the scarlet and cream white school colors of Chicago Theological Seminary is not available at this time.
Citations in the World Almanac (listed by cover date; color information is from the previous year): scarlet/cream white (1923-1935)
The Intercollegiate Bureau of Academic Costume (IBAC) probably assigned a scarlet hood lining with a cream white chevron to Chicago Theological Seminary between 1895 and 1898, but a description of this hood lining assignment for the seminary does not officially appear until an IBAC list from 1927.
