I will explain a construction of q-Catalan numbers for all finite complex reflection groups. The formula is elementary, involving only some basic invariant theory of complex reflection groups, but the construction is interesting because it features the monodromy of the monodromy of the KZ connection, and hence unusual symmetries of the irreducible representations of complex reflection groups.
