  The Fano plane is the unique linear 3-uniform hypergraph on seven vertices
and seven hyperedges. It was recently proved that, for all $n \geq 8$, the
balanced complete bipartite 3-uniform hypergraph on $n$ vertices, denoted by
$B_n$, is the 3-uniform hypergraph on $n$ vertices with the largest number of
hyperedges that does not contain a copy of the Fano plane. For sufficiently
large $r$ and $n$, we show that $B_n$ admits the largest number of $r$-edge
colorings with no rainbow copy of the Fano plane.
