  Novel order parameters for the confinement-deconfinement phase transition of
quenched QCD and fundamentally charged scalar QCD are presented. Similar to the
well-known dual condensate, they are defined via generalized matter propagators
with $U(1)$-valued boundary conditions. The order parameters are easily
accessible with functional methods. Their validity and accessibility is
explicitly demonstrated by numerical studies of the Dyson-Schwinger equations
for the matter propagators. Even in the case of heavy scalar matter, where the
propagator does not show a signature of the phase transition, a discontinuity
due to the transition can be extracted in the order parameters, establishing
also fundamentally charged scalar matter as a probe for color confinement.
