  In his 1984 AMS Memoir, George Andrews defined the family of $k$--colored
generalized Frobenius partition functions. These are denoted by $c\phi_k(n)$
where $k\geq 1$ is the number of colors in question. In that Memoir, Andrews
proved (among many other things) that, for all $n\geq 0,$ $c\phi_2(5n+3) \equiv
0\pmod{5}.$ Soon after, many authors proved congruence properties for various
$k$--colored generalized Frobenius partition functions, typically with a small
number of colors.
  In 2011, Baruah and Sarmah proved a number of congruence properties for
$c\phi_4$, all with moduli which are powers of 4. In this brief note, we add to
the collection of congruences for $c\phi_4$ by proving this function satisfies
an unexpected result modulo 5. The proof is elementary, relying on Baruah and
Sarmah's results as well as work of Srinivasa Ramanujan.
