This talk discusses the possibility of new physics within the strong gauge
interactions, specifically the idea of an extended color gauge group that is
spontaneously broken to QCD. After a brief review of the literature, three of
our recent pieces of work on coloron phenomenology are summarized. First, some
key results on coloron production to NLO at hadron colliders are described.
Next, a method of using associated production of colorons and weak vector
bosons to better determine coloron couplings is discussed. Finally, a new model
that naturally realizes flavor physics is reviewed.
