  In this note we study a conjecture by Jer\'onimo-Castro, Magazinov and
Sober\'on which generalized a question posed by Dol'nikov. Let
$F_1,F_2,\dots,F_n$ be families of translates of a convex compact set $K$ in
the plane so that each two sets from distinct families intersect. We show that,
for some $j$, $\bigcup_{i\neq j}F_i$ can be pierced by at most $4$ points. To
do so, we use previous ideas from Gomez-Navarro and Rold\'an-Pensado together
with an approximation result closely tied to the Banach-Mazur distance to the
square.
