  We construct invariants of colored links using equivariant bordism groups of
Conner and Floyd. We employ this bordism invariant to find the first examples
of topological vortex knots, the knot structure of which is protected from
decaying via topologically allowed local surgeries, i.e., by reconnections and
strand crossings permitted by the topology of the vortex-supporting medium.
Moreover, we show that, up to the aforementioned local surgeries, each
tricolored link either decays into unlinked simple loops, or can be transformed
into either a left-handed or a right-handed tricolored trefoil knot.
