  Link/knot invariants are series with integer coefficients, and it is a
long-standing problem to get them positive and possessing cohomological
interpretation. Constructing positive "superpolynomials" is not
straightforward, especially for colored invariants. A simpler alternative is a
multi-parametric generalization of the character expansion, which leads to
colored "hyperpolynomials". The third construction involves branes on resolved
conifolds, which gives rise to still another family of invariants associated
with composite representations. We revisit this triality issue in the simple
case of the Hopf link and discover a previously overlooked way to produce
positive colored superpolynomials from the DIM-governed four-point functions,
thus paving a way to a new relation between super- and hyperpolynomials.
