Citations in the World Almanac (listed by cover date; color information is from the previous year): maroon/gold (1934-1935)
The Intercollegiate Bureau of Academic Costume (IBAC) must have assigned a hood lining pattern to Calvin College between 1927 and 1948 as the college is not cited in an IBAC list until 1948, where it is described as having a hood lined maroon with a gold chevron. This description did not change in any IBAC list thereafter.
